Brain disorders are conditions that affect the brain's normal functioning, leading to changes in thinking, behavior, and emotions. These disorders can result from various factors, including genetics, injury, or infections. Common examples include Alzheimer's disease, which affects memory, and Parkinson's disease, which impacts movement. Treatment for brain disorders often involves a combination of medication, therapy, and lifestyle changes. Early diagnosis is crucial, as it can help manage symptoms and improve quality of life. Support from family and friends also plays a vital role in helping individuals cope with the challenges posed by these conditions.
