The presence of cerebral atrophy can cause dizziness. Cerebral atrophy refers to the atrophy of the brain tissue itself, where the volume of brain tissue shrinks and the number of brain cells decreases, causing the functional skills of the brain to decline continuously and the cognitive function of the individual to diminish. If diffuse cortical atrophy occurs, dementia, mental retardation, memory impairment, and also dizziness occur. Dizziness is one of the important clinical symptoms of cerebral atrophy, and early patients may experience dizziness, headache, insomnia, and excessive dreaming. The continuous reduction of nerves or cells in the brain will also affect the normal blood vessels in the brain, resulting in long-term ischemia and hypoxia in the brain, which will also cause dizziness. The enlarged ventricles and reduced volume of brain tissue affect normal cognitive function, and when patients become aware of it they will experience significant psychological disturbances and will experience dizziness due to plant nerve disturbances.
