DBS surgery may be completed in one operating session, but it is more commonly performed in two parts. In the first stage of the procedure, the surgeon will map targets in the brain using CT or MRI imaging to determine where to place the electrodes. Then, by drilling holes into the skull, the surgeon will place the electrodes into specific areas in the brain. The holes will be closed, and patients will require 1-2 days to recover in the hospital. After about two weeks, patients will undergo another surgery to have the deep brain stimulator implanted. The stimulator is usually placed under the skin around the collarbone, chest, or abdomen, and it will be connected to the DBS electrodes through a subcutaneous wire. No component of the DBS system will be visible from outside. Following stimulator implantation, patients may need to recover in the hospital for 1-2 days.

Within 2-4 weeks of the operation, doctors will program the stimulator using a wireless device. Patients will work with their doctor to determine the most effective settings for the stimulator during follow-up visits. Patients will be given a handheld device so that they can turn the stimulator on or off and adjust its settings themselves. The stimulator may have a rechargeable battery, in which case patients will be given a charging unit. Stimulator batteries generally need to be replaced in 3-5 years.

OCD frequently revolves around themes such as the fear of contracting germs or the fear of death. Common obsessions include:

• Fear of getting contaminated by people or the environment
• Extreme concern with order or precision
• Fear of death or behaviors perceived as risky
• Fear of accidents, disasters, and traumatic incidents

These obsessions and compulsions often contribute to anxiety, depression, and recurring emotions of fear and disgust. People with OCD cannot "turn off" their patterns of thought or behavior, and thus must continually grapple with urges to behave or think in a certain way, as well as the emotions associated with these urges. Some OCD patients describe their entire life as revolving around their obsessions and compulsions and this can result in their missing out on important school and social activities, travel, and family time. The impact of OCD is extensive and can even make daily activities like drinking, reading, sleeping, and eating extremely difficult.

The obsessions manifest in compulsive behaviors that can have negative implications on one's life. Some examples of compulsive behaviors include, among others:

• Excessive hand washing or showering
• Constant reordering or arranging of items
• Refusal to fly, drive, or participate in other activities
• Refusal to leave one's residence

Obsessive-compulsive disorder affects adults, adolescents, and children. OCD has been observed in children as young as five or six years of age, usually through sensitivity issues, obsessions about dirt or germs, or repeated doubts. The cause of obsessive-compulsive disorder is unknown. However, a person's likelihood of developing the condition may be increased by a number of variables such as family history, stressful life events, and pre-existing mental health disorders.

OCD is diagnosed based on a patients' reported symptoms. For example, a pediatrician or child psychiatrist may ask children (or their parents) how often they wash their hands or experience behavioral urges. Psychiatrists will evaluate patients for other symptoms and may instruct patients to describe their mental processes, thought patterns, and previous traumatic experiences.

While there is no cure for OCD, treatment can greatly improve patients' functioning in daily routines and activities. A common treatment for OCD is cognitive behavioral therapy (CBT), which helps patients identify negative patterns of thought and behavior and learn how to adjust them. Aversion therapy may also help those who have a fear of germs or contamination by forcing them to confront their fear and slowly overcome it. Many patients also benefit from counseling to address the anxiety, stress, and trauma that may accompany OCD. Other treatments for OCD include oral medications such as selective serotonin reuptake inhibitors (SSRIs, which are antidepressants) to normalize levels of a brain chemical called serotonin, which may improve OCD symptoms. Medications such as fluoxetine (Prozac) and sertraline (Zoloft) can help alleviate OCD-related behavioral urges, anxiety, and depression. Many OCD patients also find OCD support groups helpful to learn new coping strategies, to socialize, and to verbalize their emotions and experiences.

It is important to note that while OCD is a common mental health disorder, it is not a personality trait. The term "OCD" is sometimes used to informally describe someone having a tendency towards organization or orderliness. This usage is pervasive but inappropriate - OCD is a severe, life-altering condition. Some people with OCD who successfully manage their symptoms find that they may benefit from other traits that may be associated with OCD, such as high attention to detail and precision.

A comprehensive psychiatric evaluation is necessary to identify this illness, and one of the top criteria for a diagnosis of schizophrenia is that at least some of the symptoms listed above have to be present for a minimum of six months. The causes of schizophrenia are unclear, but studies have linked it to genetics, abnormalities in brain structure, and immune disorders. It has also been found to affect men and women equally, with onset typically occurring earlier in men.

Although there is no cure for schizophrenia, some treatments can help people manage their disease. For example, physicians may prescribe antipsychotics which are a group of medications that can reduce symptoms. Patients can also learn useful coping skills and get emotional support by regularly taking part in individual talk therapy and having family members participate in group therapy sessions.
