Personality

Questions of personality have vexed mankind from the dawn of personhood: can people change? How do others perceive me? What is the difference between normal and pathological behavior? One's personality is so pervasive and all-important that it presents a clinical paradox of sorts: it is hard to assess our own personality, impossible to overlook that of others.

Obessive-Compulsive Disorder

Obsessive-Compulsive Disorder (OCD) is a potentially disabling anxiety disorder. People afflicted with OCD become trapped in a pattern of repetitive, senseless thoughts and behaviors that are very difficult to overcome.

Left untreated, a severe case of OCD can destroy a person's capacity to function at work or school—or to lead a comfortable existence at home.
