Introduction
In general, feelings of mental numbness and dullness may be caused by factors such as lack of sleep, high levels of stress, neurasthenia, insufficient cerebral blood supply, or cerebral infarction. If a patient frequently stays up late, it may lead to sleep deprivation, preventing the brain from getting adequate rest, which could result in symptoms such as dizziness, mental fogginess, and decreased memory.
In general, feelings of mental numbness and dullness may be caused by factors such as lack of sleep, high mental stress, neurasthenia, insufficient cerebral blood supply, or cerebral infarction. A detailed analysis is as follows:
1. Sleep deprivation
If a patient frequently stays up late in daily life, it may lead to insufficient sleep, preventing the brain from getting adequate rest. This could result in symptoms such as dizziness, mental fogginess, and decreased memory. It is recommended that patients maintain healthy lifestyle habits, avoid staying up late, and ensure sufficient sleep.
2. High mental stress
If a patient experiences excessive mental stress in daily life, it may cause excessive fatigue of the brain, leading to the aforementioned symptoms. Patients are advised to engage in appropriate outdoor walking, which can help relieve stress and maintain a positive mood. When necessary, patients should seek medical attention promptly and receive psychological counseling under the guidance of a healthcare professional.
3. Neurasthenia
If a patient has long-term excessive mental stress, it may lead to neurasthenia, characterized by symptoms such as mental hyperexcitability and mental fatigue. Patients may take medications such as paroxetine hydrochloride tablets or sertraline hydrochloride tablets orally as prescribed by a doctor to improve symptoms. They should also relax their minds and avoid excessive mental stress.
4. Insufficient cerebral blood supply
If a patient smokes regularly or drinks heavily over a long period, it may lead to cerebral arteriosclerosis, impairing cerebral circulation and easily causing inadequate blood supply to the brain. Symptoms may include dizziness, headache, and sleep disturbances. Patients may take medications such as enteric-coated aspirin tablets or nimodipine tablets as directed by a physician to improve their condition. Additionally, they should quit smoking and drinking and ensure adequate rest.
5. Cerebral infarction
Cerebral infarction refers to localized ischemic necrosis or softening of brain tissue caused by impaired cerebral blood supply due to ischemia and hypoxia. It may be associated with long-term smoking and alcohol consumption, diabetes, hypertension, and other factors. Patients may experience sensory disturbances, nausea, vomiting, and other symptoms. It is recommended that patients receive treatment under a doctor's guidance using medications such as enteric-coated aspirin tablets or clopidogrel hydrogen sulfate tablets. Carotid endarterectomy may also be considered as a treatment option.
In addition, these symptoms may also be related to conditions such as carotid artery stenosis. Patients are advised to seek timely medical evaluation at a hospital to determine the exact cause, prevent disease progression, and avoid more severe damage to the brain.
