Mental Health: Symptoms, Conditions, Treatment & Support
Learn about common mental health conditions, warning signs, possible causes, diagnosis, treatment options and when it may be helpful to talk with a mental health professional.
What Is Mental Health?
Mental health refers to emotional, psychological and social well-being. It can influence how a person thinks, feels, behaves, manages stress, relates to others and functions in everyday life.
Mental health conditions can affect mood, thinking, behavior, relationships, sleep, concentration and daily functioning. They can take many forms, including anxiety disorders, depression, bipolar disorder, schizophrenia and other conditions.
