Mental health affects how people think, feel and act. It is important at every stage of life from childhood through adulthood. Approximately 1 in 25 adults and 1 in 5 youth experience a mental illness each year. Common mental illnesses include anxiety disorders, depression, and ADHD. Anxiety disorders are very common and affect people of all ages. Depression can occur at any age from preschool through elderly. ADHD affects about 10% of school-aged children and causes inattention, impulsivity and hyperactivity. The causes of these conditions vary and can include genetics, medical conditions, life changes and stressors. Non-profit organizations like Mental Health America and NAMI work to promote mental health awareness, education, advocacy and recovery
