What causes dizziness and mental confusion?

Possible causes of dizziness and mental fogginess may include: Physiological factors: - Prolonged fatigue or lack of sleep, leading to brain fatigue. - Hunger or low blood sugar, affecting the brain's energy supply. Disease-related factors: 1. Anemia: Reduced red blood cells or hemoglobin result in insufficient oxygen supply to the brain. 2. Cerebrovascular diseases: Conditions such as inadequate cerebral blood flow or cerebral arteriosclerosis impair brain circulation. 3. High or low blood pressure: Abnormal blood pressure fluctuations may lead to insufficient or excessive blood supply to the brain. 4. Cervical spondylosis: Cervical spine problems may compress blood vessels or nerves, affecting blood supply to the brain.
