In some cases, a primary care doctor can prescribe medications to relieve depression symptoms. However, many people need to see a doctor who specializes in diagnosing and treating mental health conditions (psychiatrist). Many people with depression also benefit from seeing a psychologist or other mental health counselor. Usually the most effective treatment for depression is a combination of medication and psychotherapy.

If you have severe depression, a doctor, loved one or guardian may need to guide your care until you’re well enough to participate in decision making. You may need a hospital stay, or you may need to participate in an outpatient treatment program until your symptoms improve.

Here’s a closer look at your depression treatment options.

Medications
A number of antidepressant medications are available to treat depression. There are several different types of antidepressants. Antidepressants are generally categorized by how they affect the naturally occurring chemicals in your brain to change your mood.

Types of antidepressants include:
Selective serotonin reuptake inhibitors (SSRIs). Many doctors start depression treatment by prescribing an SSRI. These medications are safer and generally cause fewer bothersome side effects than other types of antidepressants. SSRIs include fluoxetine (Prozac), paroxetine (Paxil), sertraline (Zoloft), citalopram (Celexa) and escitalopram (Lexapro). The most common side effects include decreased sexual desire and delayed orgasm. Other side effects may go away as your body adjusts to the medication. They can include digestive problems, jitteriness, restlessness, headache and insomnia.
Serotonin and norepinephrine reuptake inhibitors (SNRIs). These medications include duloxetine (Cymbalta), venlafaxine (Effexor) and desvenlafaxine (Pristiq). Side effects are similar to those caused by SSRIs. In high doses these medications can cause increased sweating and dizziness. People with liver disease shouldn’t take duloxetine.
Norepinephrine and dopamine reuptake inhibitors (NDRIs). Bupropion (Wellbutrin) falls into this category. It’s one of the few antidepressants that doesn’t cause sexual side effects. At high doses, bupropion may increase your risk of having seizures.
Atypical antidepressants. These medications are called atypical because they don’t fit neatly into another antidepressant category. They include trazodone (Desyrel) and mirtazapine (Remeron). Both of these antidepressants are sedating and are usually taken in the evening. In some cases, one of these medications is added to other antidepressants to help with sleep.
Tricyclic antidepressants. These antidepressants have been used for years and are generally as effective as newer medications. But because they tend to have more numerous and more severe side effects, a tricyclic antidepressant generally isn’t prescribed unless you’ve tried an SSRI first without an improvement in your depression. Side effects can include low blood pressure, dry mouth, blurred vision, constipation, urinary retention, fast heartbeat and confusion. Older adults taking these medications are susceptible to memory problems, confusion and hallucinations. Tricyclic antidepressants are also known to cause weight gain.
Monoamine oxidase inhibitors (MAOIs). MAOIs — such as tranylcypromine (Parnate) and phenelzine (Nardil) — are usually prescribed as a last resort, when other medications haven’t worked. That’s because MAOIs can have serious harmful side effects. They require a strict diet because of dangerous (or even deadly) interactions with foods such as certain cheeses, pickles and wines and some medications including decongestants. Selegiline (Emsam) is a newer MAOI that you stick on your skin as a patch rather than swallowing. It may cause fewer side effects than other MAOIs.
Other medication strategies. Your doctor may suggest other medications to treat your depression. These may include stimulants, mood-stabilizing medications, anti-anxiety medications or antipsychotic medications. In some cases, your doctor may recommend combining two or more antidepressants or other medications for better effect. This strategy is known as augmentation.

Finding the right medication
Everyone’s different, so finding the right medication or medications for you will likely take some trial and error. This requires patience, as some medications need eight weeks or longer to take full effect and for side effects to ease as your body adjusts. If you have bothersome side effects, don’t stop taking an antidepressant without talking to your doctor first. Some antidepressants can cause withdrawal symptoms unless you slowly taper off your dose, and quitting suddenly may cause a sudden worsening of depression. Don’t give up until you find an antidepressant or medication that’s suitable for you — you’re likely to find one that works and that doesn’t have intolerable side effects.

If antidepressant treatment doesn’t seem to be working, your doctor may recommend a blood test to check for specific genes that affect how your body uses antidepressants. The cytochrome P450 (CYP450) genotyping test is one example of this type of exam. Genetic testing of this kind can help predict how well your body can or can’t process (metabolize) a medication. This may help identify which antidepressant might be a good choice for you. These genetic tests aren’t widely available, so they’re an option only for people who have access to a clinic that offers them.

Antidepressants and pregnancy
If you’re pregnant or breast-feeding, some antidepressants may pose an increased health risk to your unborn child or nursing child. Talk to your doctor if you become pregnant or are planning on becoming pregnant.

Antidepressants and increased suicide risk
Although most antidepressants are generally safe, be careful when taking them. The Food and Drug Administration (FDA) now requires that all antidepressant medications carry black box warnings. These are the strictest warnings that the FDA can issue for prescription medications.

The antidepressant warnings note that in some cases, children, adolescents and young adults ages 18 to 24 may have an increase in suicidal thoughts or behavior when taking antidepressants, especially in the first few weeks after starting an antidepressant or when the dose is changed. Because of this risk, people in these age groups must be closely monitored by loved ones, caregivers and health care providers while taking antidepressants. If you — or someone you know — has suicidal thoughts when taking an antidepressant, immediately contact your doctor or get emergency help.

Again, make sure you understand the risks of the various antidepressants. Working together, you and your doctor can explore options to get your depression symptoms under control.

Psychotherapy
Psychological counseling is another key depression treatment. Psychotherapy is a general term for a way of treating depression by talking about your condition and related issues with a mental health provider. Psychotherapy is also known as therapy, talk therapy, counseling or psychosocial therapy.

Through these talk sessions, you learn about the causes of depression so that you can better understand it. You also learn how to identify and make changes in unhealthy behavior or thoughts, explore relationships and experiences, find better ways to cope and solve problems, and set realistic goals for your life. Psychotherapy can help you regain a sense of happiness and control in your life and help ease depression symptoms such as hopelessness and anger. It may also help you adjust to a crisis or other current difficulty.

There are several types of psychotherapy that are effective for depression. Cognitive behavioral therapy is one of the most commonly used therapies. This type of therapy helps you identify negative beliefs and behaviors and replace them with healthy, positive ones. It’s based on the idea that your own thoughts — not other people or situations — determine how you feel or behave. Even if an unwanted situation doesn’t change, you can change the way you think and behave in a positive way. Interpersonal therapy and psychodynamic psychotherapy are other types of counseling commonly used to treat depression.

Electroconvulsive therapy (ECT)
In ECT, electrical currents are passed through the brain. This procedure is thought to affect levels of neurotransmitters in your brain. Although many people are leery of ECT and its side effects, it typically offers immediate relief of even severe depression when other treatments don’t work. It’s unclear how this therapy relieves the signs and symptoms of depression. The most common side effect is confusion, which can last from a few minutes to several hours. Some people also have memory loss.

ECT is usually used for people who don’t get better with medications and for those at high risk of suicide. ECT may be an option if you have severe depression when you’re pregnant and can’t take your regular medications. It can also be an effective treatment for older adults who have severe depression and can’t take antidepressants for health reasons.

Hospitalization and residential treatment programs
In some people, depression is so severe that a hospital stay is needed. Inpatient hospitalization is may be necessary if you aren’t able to care for yourself properly or when you’re in immediate danger of harming yourself or someone else. Getting psychiatric treatment at a hospital can help keep you calm and safe until your mood improves. Partial hospitalization or day treatment programs also are helpful for some people. These programs provide the support and counseling you need while you get symptoms under control.

Other treatments for depression
If standard depression treatment hasn’t been effective, your psychiatrist may consider whether you might benefit from a less commonly used procedure, such as:
Vagus nerve stimulation. This treatment uses electrical impulses with a surgically implanted pulse generator to affect mood centers of the brain. This may be an option if you have chronic, treatment-resistant depression.
Transcranial magnetic stimulation. With this treatment, powerful magnetic fields are used to alter brain activity. A large electromagnetic coil is held against your scalp near your forehead to produce an electrical current in your brain.

Lifestyle and home remedies
Depression generally isn’t an illness that you can treat on your own. But you can do some things for yourself that will help. In addition to professional treatment, follow these self-care steps:
Stick to your treatment plan. Don’t skip psychotherapy sessions or appointments, even if you don’t feel like going. Even if you’re feeling well, resist any temptation to skip your medications. If you stop, depression symptoms may come back, and you could also experience withdrawal-like symptoms.
Learn about depression. Education about your condition can empower you and motivate you to stick to your treatment plan.
Pay attention to warning signs. Work with your doctor or therapist to learn what might trigger your depression symptoms. Make a plan so that you know what to do if your symptoms get worse. Contact your doctor or therapist if you notice any changes in symptoms or how you feel. Ask family members or friends to help watch for warning signs.
Get exercise. Physical activity reduces depression symptoms. Consider walking, jogging, swimming, gardening or taking up another activity you enjoy.
Avoid alcohol and illicit drugs. It may seem like alcohol or drugs lessen depression symptoms, but in the long run they generally worsen symptoms and make depression harder to treat.
Get plenty of sleep. Sleeping well is especially important when you’re depressed. If you’re having trouble sleeping, talk to your doctor about what you can do.

Down syndrome, or Down’s syndrome (primarily in the United Kingdom), trisomy 21, or trisomy G, is a chromosomal disorder caused by the presence of all or part of an extra 21st chromosome. It is named after John Langdon Down, the British physician who described the syndrome in 1866. The disorder was identified as a chromosome 21 trisomy by Jérôme Lejeune in 1959. The condition is characterized by a combination of major and minor differences in structure. Often Down syndrome is associated with some impairment of cognitive ability and physical growth, and a particular set of facial characteristics. Down syndrome in a fetus can be identified with amniocentesis during pregnancy, or in a baby at birth.

Individuals with Down syndrome tend to have a lower than average cognitive ability, often ranging from mild to moderate developmental disabilities. A small number have severe to profound mental disability. The incidence of Down syndrome is estimated at 1 per 800 to 1,000 births, although it is statistically much more common with older mothers. Other factors may also play a role.

Many of the common physical features of Down syndrome may also appear in people with a standard set of chromosomes, including microgenia (an abnormally small chin), an unusually round face, macroglossia (protruding or oversized tongue), an almond shape to the eyes caused by an epicanthic fold of the eyelid, upslanting palpebral fissures (the separation between the upper and lower eyelids), shorter limbs, a single transverse palmar crease (a single instead of a double crease across one or both palms, also called the Simian crease), poor muscle tone, and a larger than normal space between the big and second toes. Health concerns for individuals with Down syndrome include a higher risk for congenital heart defects, gastroesophageal reflux disease, recurrent ear infections, obstructive sleep apnea, and thyroid dysfunctions.

Early childhood intervention, screening for common problems, medical treatment where indicated, a conducive family environment, and vocational training can improve the overall development of children with Down syndrome. Although some of the physical genetic limitations of Down syndrome cannot be overcome, education and proper care will improve quality of life.

A sleep disorder (somnipathy) is a medical disorder of the sleep patterns of a person or animal. Some sleep disorders are serious enough to interfere with normal physical, mental and emotional functioning. A test commonly ordered for some sleep disorders is the polysomnography.T7925N89JGWB

The most common sleep disorders include:
Primary insomnia: Chronic difficulty in falling asleep and/or maintaining sleep when no other cause is found for these symptoms.
Bruxism: Involuntarily grinding or clenching of the teeth while sleeping.
Delayed sleep phase syndrome (DSPS): inability to awaken and fall asleep at socially acceptable times but no problem with sleep maintenance, a disorder of circadian rhythms. Other such disorders are advanced sleep phase syndrome (ASPS) and Non-24-hour sleep-wake syndrome (Non-24), both much less common than DSPS.
Hypopnea syndrome: Abnormally shallow breathing or slow respiratory rate while sleeping.
Narcolepsy: Excessive daytime sleepiness (EDS) often culminating in falling asleep spontaneously but unwillingly at inappropriate times.
Cataplexy: a sudden weakness in the motor muscles that can result in collapse to the floor.
Night terror: Pavor nocturnus, sleep terror disorder: abrupt awakening from sleep with behavior consistent with terror.
Parasomnias: Disruptive sleep-related events involving inappropriate actions during sleep stages – sleep walking and night-terrors are examples.
Periodic limb movement disorder (PLMD): Sudden involuntary movement of arms and/or legs during sleep, for example kicking the legs. Also known as nocturnal myoclonus. See also Hypnic jerk, which is not a disorder.
Rapid eye movement behavior disorder (RBD): Acting out violent or dramatic dreams while in REM sleep.
Restless legs syndrome (RLS): An irresistible urge to move legs. RLS sufferers often also have PLMD.
Situational circadian rhythm sleep disorders: shift work sleep disorder (SWSD) and jet lag.
Obstructive sleep apnea: Obstruction of the airway during sleep, causing lack of sufficient deep sleep; often accompanied by snoring. Other forms of sleep apnea are less common.
Sleep paralysis: is characterized by temporary paralysis of the body shortly before or after sleep. Sleep paralysis may be accompanied by visual, auditory or tactile hallucinations. Not a disorder unless severe. Often seen as part of Narcolepsy.
Sleepwalking or somnambulism: Engaging in activities that are normally associated with wakefulness (such as eating or dressing), which may include walking, without the conscious knowledge of the subject.
Nocturia: A frequent need to get up and go to the bathroom to urinate at night. It differs from Enuresis, or bed-wetting, in which the person does not arouse from sleep, but the bladder nevertheless empties.
Somniphobia: a dread of sleep.

Dependent personality disorder (DPD), formerly known as asthenic personality disorder, is a personality disorder that is characterized by a pervasive psychological dependence on other people. The difference between a ‘dependent personality’ and a ‘dependent personality disorder’ is somewhat subjective, which makes diagnosis sensitive to cultural influences such as gender role expectations.

Obsessive-compulsive disorder symptoms include both obsessions and compulsions.

OCD obsession symptoms
OCD obsessions are repeated, persistent and unwanted ideas, thoughts, images or impulses that you have involuntarily and that seem to make no sense. These obsessions typically intrude when you’re trying to think of or do other things.

Obsessions often have themes to them, such as:
Fear of contamination or dirt
Having things orderly and symmetrical
Aggressive or horrific impulses
Sexual images or thoughts

OCD symptoms involving obsessions may include:
Fear of being contaminated by shaking hands or by touching objects others have touched
Doubts that you’ve locked the door or turned off the stove
Thoughts that you’ve hurt someone in a traffic accident
Intense distress when objects aren’t orderly or facing the right way
Images of hurting your child
Impulses to shout obscenities in inappropriate situations
Avoidance of situations that can trigger obsessions, such as shaking hands
Replaying pornographic images in your mind
Dermatitis because of frequent hand washing
Skin lesions because of picking at your skin
Hair loss or bald spots because of hair pulling

OCD compulsion symptoms
OCD compulsions are repetitive behaviors that you feel driven to perform. These repetitive behaviors are meant to prevent or reduce anxiety or distress related to your obsessions. For instance, if you believe you ran over someone in your car, you may return to the apparent scene over and over because you just can’t shake your doubts. You may also make up rules or rituals to follow that help control the anxiety you feel when having obsessive thoughts.

As with OCD obsessions, compulsions typically have themes, such as:
Washing and cleaning
Counting
Checking
Demanding reassurances
Performing the same action repeatedly
Orderliness

OCD symptoms involving compulsions may include:
Hand washing until your skin becomes raw
Checking doors repeatedly to make sure they’re locked
Checking the stove repeatedly to make sure it’s off
Counting in certain patterns
Making sure all your canned goods face the same way

When to see a doctor
There’s a difference between being a perfectionist and having obsessive-compulsive disorder. Perhaps you keep the floors in your house so clean that you could eat off them. Or you like your knickknacks arranged just so. That doesn’t necessarily mean that you have obsessive-compulsive disorder.

Obsessive-compulsive disorder can be so severe and time-consuming that it literally becomes disabling. You may be able to do little else but spend time on your obsessions and compulsions — washing your hands for hours each day, for instance. With OCD, you may have a low quality of life because the condition rules most of your days. You may be very distressed but feel powerless to stop your urges. Most adults can recognize that their obsessions and compulsions don’t make sense. Children, however, may not understand what’s wrong.

If your obsessions and compulsions are affecting your life, see your doctor or mental health provider. It’s common for people with OCD to be ashamed and embarrassed about the condition. But even if your rituals are deeply ingrained, treatment can help.

Obsessive–compulsive disorder (OCD) is a mental disorder characterized by intrusive thoughts that produce anxiety, by repetitive behaviors aimed at reducing anxiety, or by a combination of such thoughts and behaviors. The symptoms of this anxiety disorder may include touching objects a certain number of times to ward off a feeling of dread. These symptoms can be alienating and time-consuming, and often cause emotional and economic loss. The acts of those who have OCD may appear paranoid and come across to others as psychotic. However, OCD sufferers generally recognize their thoughts and resulting actions are irrational, and they may become further distressed by this realization.

OCD is the fourth-most common mental disorder and is diagnosed nearly as often as asthma and diabetes mellitus. In the United States, one in 50 adults have OCD. The phrase “obsessive–compulsive” has become part of the English lexicon, and is often used in an informal or caricatured manner to describe someone who is meticulous, perfectionistic, absorbed in a cause, or otherwise fixated on something or someone.[3] Although these signs may be present in OCD, a person who exhibits them does not necessarily have OCD, and may instead have obsessive–compulsive personality disorder (OCPD), an autism spectrum disorder, or no clinical condition. Multiple psychological and biological factors may be involved in causing obsessive–compulsive syndromes.

Antisocial Personality Disorder (ASPD or APD) is defined by the American Psychiatric Association’s Diagnostic and Statistical Manual as “…a pervasive pattern of disregard for, and violation of, the rights of others that begins in childhood or early adolescence and continues into adulthood.”

The individual must be age 18 or older, as well as have a documented history of a conduct disorder before the age of 15. People having antisocial personality disorder are sometimes referred to as “sociopaths” and “psychopaths”.

Anxiety is a psychological and physiological state characterized by cognitive, somatic, emotional, and behavioral components. These components combine to create an unpleasant feeling that is typically associated with uneasiness, apprehension, fear, or worry. Anxiety is a generalized mood condition that can often occur without an identifiable triggering stimulus. As such, it is distinguished from fear, which occurs in the presence of an observed threat. Additionally, fear is related to the specific behaviors of escape and avoidance, whereas anxiety is the result of threats that are perceived to be uncontrollable or unavoidable.

Another view is that anxiety is “a future-oriented mood state in which one is ready or prepared to attempt to cope with upcoming negative events” suggesting that it is a distinction between future vs. present dangers that divides anxiety and fear. Anxiety is considered to be a normal reaction to stress. It may help a person to deal with a difficult situation, for example at work or at school, by prompting one to cope with it. When anxiety becomes excessive, it may fall under the classification of an anxiety disorder.

Substance abuse, also known as drug abuse, refers to a maladaptive pattern of use of a substance that is not considered dependent. The term “drug abuse” does not exclude dependency, but is otherwise used in a similar manner in nonmedical contexts. The terms have a huge range of definitions related to taking a psychoactive drug or performance enhancing drug for a non-therapeutic or non-medical effect. All of these definitions imply a negative judgment of the drug use in question (compare with the term responsible drug use for alternative views). Some of the drugs most often associated with this term include alcohol, amphetamines, barbiturates, benzodiazepines, cocaine, methaqualone, and opioids. Use of these drugs may lead to criminal penalty in addition to possible physical, social, and psychological harm, both strongly depending on local jurisdiction. Other definitions of drug abuse fall into four main categories: public health definitions, mass communication and vernacular usage, medical definitions, and political and criminal justice definitions.

A mental disorder or mental illness is a psychological or behavioral pattern associated with distress or disability that occurs in an individual and is not a part of normal development or culture. The recognition and understanding of mental health conditions has changed over time and across cultures, and there are still variations in the definition, assessment, and classification of mental disorders, although standard guideline criteria are widely accepted.

Over a third of people in most countries report meeting criteria for the major categories at some point in their life. The causes are often explained in terms of a diathesis-stress model and biopsychosocial model. Services are based in psychiatric hospitals or in the community, and mental health professionals diagnose individuals by various methods, often relying on observation and questioning in interview.

Psychotherapy and psychiatric medication are two major treatment options as are social interventions, peer support and self-help. In some cases there may be involuntary detention and involuntary treatment where legislation allows. Stigma and discrimination add to the suffering associated with the disorders, and various social movements campaign for change.

The Diagnostic and Statistical Manual of Mental Disorders (DSM) is published by the American Psychiatric Association and provides a common language and standard criteria for the classification of mental disorders. It is used in the United States and in varying degrees around the world, by clinicians, researchers, psychiatric drug regulation agencies, health insurance companies, pharmaceutical companies and policy makers.

The DSM has attracted controversy and criticism as well as praise. There have been five revisions since it was first published in 1952, gradually including more mental disorders, though some have been removed and are no longer considered to be mental disorders.

The manual evolved from systems for collecting census and psychiatric hospital statistics, and from a manual developed by the US Army, and was dramatically revised in 1980. The last major revision was the fourth edition (“DSM-IV”), published in 1994, although a “text revision” was produced in 2000. The fifth edition (“DSM-V”) is currently in consultation, planning and preparation, due for publication in May 2013.

Asperger syndrome or Asperger’s syndrome is an autism spectrum disorder, and people with it therefore show significant difficulties in social interaction, along with restricted and repetitive patterns of behavior and interests. It differs from other autism spectrum disorders by its relative preservation of linguistic and cognitive development. Although not required for diagnosis, physical clumsiness and atypical use of language are frequently reported.
