Cerebral hemisphere degeneration is a condition where the brain’s cerebral hemispheres, the two halves of the brain, deteriorate over time. This degeneration can lead to various neurological symptoms affecting movement, cognition, and other functions. In this comprehensive guide, we’ll explore the types, causes, symptoms, diagnostic tests, treatments, and prevention methods related to cerebral hemisphere degeneration.
Types of Cerebral Hemisphere Degeneration
- Frontotemporal Dementia (FTD): This type primarily affects the frontal and temporal lobes of the brain, leading to changes in behavior, personality, and language abilities.
- Alzheimer’s Disease: While Alzheimer’s primarily affects memory, it also involves degeneration of the cerebral hemispheres.
- Huntington’s Disease: This genetic disorder causes progressive degeneration of nerve cells in the brain, particularly in the basal ganglia and cerebral cortex.
Causes of Cerebral Hemisphere Degeneration
