What causes memory loss?

The causes of memory decline are complex and varied, mainly including the following aspects: 1. Physiological factors: such as age-related brain function degeneration, impaired brain function due to lack of sleep, and long-term late nights or irregular sleep schedules. 2. Psychological factors: psychological issues such as excessive stress, emotional instability (e.g., depression, anxiety), neurasthenia, and autonomic nervous system disorders can all negatively affect memory. 3. Lifestyle habits: unhealthy dietary habits (e.g., nutritional imbalance), overreliance on electronic devices, and lack of physical activity may also lead to memory decline. 4. Disease-related factors: conditions such as thyroid disorders, Alzheimer's disease, depression, chronic sinusitis, and cerebral arteriosclerosis can directly impact brain function, leading to memory loss.
