01

Understand Neurocognitive Disorders

Neurocognitive disorders are a group of illnesses that primarily affect cognitive abilities of individuals. This includes learning, memory, perception, and problem-solving skills.

Overview of Alzheimer’s Disease

Alzheimer's disease is the most common type of neurocognitive disorder, especially prevalent among the elderly. It's a progressive disease that impairs memory and cognitive functions. Its precise etiology is unknown, but both genetic and environmental factors seem to contribute.

Clinical Features of Alzheimer’s Disease

The clinical features of Alzheimer's disease usually start with mild memory loss, problems with language, and mood changes. As the disease progresses, these symptoms become more severe and other symptoms like difficulty swallowing, loss of bowel or bladder control, and confusion or disorientation can occur. These symptoms often get worse over time and can severely affect an individual's ability to perform day-to-day activities.

Course of Alzheimer’s Disease

Alzheimer's disease is typically divided into three stages: mild (early-stage), moderate (middle-stage), and severe (late-stage). The disease progresses through these stages at different rates in different individuals. The average lifespan of a person with Alzheimer's after diagnosis is between 4 to 8 years, but some people may live up to 20 years.
