Concept
Dementia is a broad category of brain diseases that cause a long-term and often gradual decrease in the ability to think and remember, significantly affecting daily functioning. It is not a single disease but a syndrome that involves a decline in memory, reasoning, or other cognitive skills, often accompanied by changes in mood, perception, and behavior.
Age-related cognitive decline refers to the gradual decrease in cognitive abilities such as memory, attention, and problem-solving skills that occurs as individuals age. While it is a natural part of aging, lifestyle factors and interventions like physical exercise, mental stimulation, and a healthy diet can mitigate its effects.
Concept
Ventricular dilation refers to the enlargement of the ventricles in the brain, which can be a sign of various neurological conditions, including hydrocephalus and neurodegenerative diseases. This condition is often detected through imaging techniques and can lead to increased intracranial pressure, affecting brain function.
