Alzheimer’s disease is a progressive neurological disorder that affects memory, thinking, and behavior. It is caused by abnormal protein buildup in the brain, leading to nerve cell damage and cognitive decline. Diagnosis includes neurological exams, brain imaging, and cognitive tests. While there is no cure, early intervention, medications, cognitive therapy, and lifestyle modifications can help manage symptoms and improve quality of life. Seeking care at a trusted mental health rehab center ensures expert guidance and support for patients and caregivers.
