Adjustment disorder (AjD) is among the most often diagnosed mental disorders in clinical practice. Studies show that the prevalence is around 1%–2%. AjD is time limited, although stressors may be ongoing, resulting in longer symptom duration and a high risk for suicidality.
Women show markedly higher prevalence rates of major depression, dysthymia, generalised anxiety and panic disorders as well as social and specific phobias than men. Men, on the other hand, show higher prevalence rates of antisocial personality disorder and substance dependence.
Schizophrenia can be thought of as a group of chronic disorders that are often neuro-developmentally based and marked by progressive brain changes, tissue loss (both grey and white matter), and increases in ventricular volume that have been associated with functional impairment.
Clinicians are often asked to assess functional impairment in psychiatric patients for vocational, academic, or benefits-related purposes, but this is often no simple task.
A population study found mood lability in 38% of children with ADHD.
