Mental Illness

Mental illness, also known as mental health disorders, refers to a wide range of mental health conditions, impacting how you think, feel, and behave. Globally, approximately 1 in 8 people live with a mental disorder. These conditions vary, and though effective prevention and treatment options exist, many people lack access to effective mental health care.

Cognitive Disorders

Cognitive disorders affect mental functioning, including memory, learning, decision-making, and perception. They can result from injury, illness, or degenerative conditions like dementia, and treatment may involve medication and therapy.

Obsessive Compulsive Disorder

Obsessive-compulsive disorder (OCD) is a prevalent and chronic mental health condition characterized by recurrent obsessive thoughts, referred to as ruminations, and compulsive behaviors. These symptoms can significantly disrupt daily life and cause distress.

Schizophrenia

The cause of schizophrenia remains uncertain, but it's believed to result from a mix of genetics, environment, and changes in brain chemistry and structure. Schizophrenia is marked by thoughts or experiences detached from reality, disorganized speech or behavior, and reduced engagement in daily life.
