What causes poor memory?
Generally, poor memory may be caused by aging, stress and anxiety, unhealthy lifestyle habits, vitamin B12 deficiency, Alzheimer's disease, and other factors. Symptomatic management through general treatments, medication, and other methods is necessary. If experiencing discomfort, it is recommended to seek timely medical advice and undergo corresponding treatments under a doctor's guidance. A detailed analysis is as follows:

1. Aging
With advancing age, various physiological functions in the human body gradually decline, and brain function is no exception. The number of brain cells decreases, and neural connections weaken, leading to a natural decline in memory. This is a normal phenomenon of physiological aging and typically does not cause significant disruption to daily life. It is recommended to maintain a healthy lifestyle, such as balanced nutrition, moderate exercise, and sufficient sleep, to delay the rate of memory decline.
2. Stress and Anxiety
Stress and anxiety can trigger the release of large amounts of cortisol in the body. Excessive cortisol can negatively affect the hippocampus in the brain. Chronic stress and anxiety not only damage neurons in the hippocampus but also impact the connections between neurons, leading to memory impairment. Symptoms may also include sleep disturbances, mood swings, and difficulty concentrating. It is recommended to adopt effective stress management and relaxation techniques, such as deep breathing, meditation, yoga, and progressive muscle relaxation exercises, to help reduce stress levels.
3. Unhealthy Lifestyle Habits
Unhealthy habits, such as chronic late-night stays, insufficient sleep, and an unbalanced diet, can lead to excessive brain fatigue, malnutrition, and poor blood circulation. These issues can impair normal brain function and memory, potentially accompanied by symptoms such as low energy, difficulty concentrating, and physical fatigue. It is recommended to change unhealthy lifestyle habits, maintain a regular sleep schedule, and eat a balanced diet to help improve symptoms.
4. Vitamin B12 Deficiency
Vitamin B12 protects nerve fibers and accelerates the conduction of nerve impulses. A deficiency in vitamin B12 can impair the synthesis of nerve myelin sheaths, affecting the normal function of nerve fibers, which in turn impacts memory. Additional symptoms may include anemia and neurological symptoms such as numbness in the hands and feet or unsteady gait. It is recommended to use medications such as adenosylcobalamin tablets, methylcobalamin tablets, or vitamin B12 tablets under a doctor's guidance for treatment.
5. Alzheimer's Disease
Alzheimer's disease is a common neurodegenerative disorder. In affected individuals, abnormal amyloid plaques and neurofibrillary tangles develop in the brain. These abnormal structures disrupt normal connections between neurons, leading to a gradual loss of memory and other cognitive functions. Symptoms may also include language impairments, disorientation, and impaired executive function. It is recommended to use medications such as donepezil hydrochloride tablets, rivastigmine tartrate capsules, or memantine hydrochloride tablets under a doctor's guidance for treatment.
It is recommended to consume more foods rich in protein, vitamins, and minerals, such as fish, nuts, and fresh fruits and vegetables, to provide essential nutrients for the brain.
