Do elderly people with brain atrophy experience dizziness?
If a patient exhibits atrophy of the cerebral cortex, elderly individuals generally do not show clinical symptoms of dizziness. The main manifestations are cognitive impairments, such as a decline in memory, computational ability, and judgment, as well as decreased executive functions. Some severe cases may even show personality changes and exhibit mental symptoms. If the patient has significant cerebellar atrophy, it is possible for them to experience dizziness, such as in cases of multiple system atrophy causing cerebellar atrophy, where the elderly may notably suffer from dizziness, which is related to changes in body position, particularly making them prone to dizziness when standing.
What should not be eaten in case of brainstem hemorrhage?
Firstly, patients with brainstem hemorrhage should avoid eating foods that are difficult to digest. This is because these patients can easily develop acute gastric mucosal lesions, leading to decreased gastrointestinal function. If they consume harder foods, it could increase the burden on their digestive function, which is detrimental to recovery. Secondly, patients with brainstem hemorrhage should also avoid cold items, such as drinking cold beverages or eating ice cream, as these can easily cause diarrhea. Thirdly, patients with brainstem hemorrhage should not eat overly salty foods, such as pickles, salted meat, salted fish, and so on. These items can cause an increase in blood pressure, potentially exacerbating the brainstem hemorrhage. Fourthly, avoid overly greasy foods as they can increase blood lipids, which is also unfavorable for the recovery from a brainstem hemorrhage. Fifthly, patients with brainstem hemorrhage should not smoke or drink alcohol, as these have no beneficial effect on their condition and could instead accelerate the progression of the disease.
incidence of senile dementia
Dementia in the elderly has a very noticeable high incidence trend worldwide and in China, with many people over the age of 65 suffering from this disease. Statistics show that in Western countries, the incidence of dementia in the elderly might be around 3%-8%. In China, the incidence among the elderly over 65 may also be around 5%. Therefore, the number of elderly people suffering from this disease is very large, and thus it is essential to pay attention to this disease. This disease is mainly caused by the death of nerve cells due to many reasons. Currently, there is no effective cure for this disease, but there are some drugs that can alleviate the symptoms. These drugs mainly include cholinesterase inhibitors, which can increase the content of acetylcholine in the brain, improving the level of cognitive function in patients. Additionally, symptomatic treatment should be noted to prevent lung infections, malnutrition, and other complications in the elderly.
Care measures for dementia in the elderly
Dementia in the elderly is the most common neurodegenerative disease in neurology, mainly referring to the irreversible death of neuronal cells caused by various reasons, which poses a significant clinical hazard and lacks effective treatment methods. Therefore, nursing measures become very important. The main nursing measures include, First, ensuring the patient's nutrition. In the later stages, elderly patients may have no regular diet and cannot take care of themselves. Therefore, ensuring sufficient energy intake and enough protein intake is very important. Malnutrition can easily lead to various complications, leading to the patient's death. Second, it's important to equip elderly people with commonly used contact numbers and addresses in their pockets to prevent them from getting lost and creating dangerous situations. Third, when elderly people are at home, it is crucial to keep the kitchen door closed to prevent them from turning on the gas and forgetting to turn it off. Fourth, patients with dementia are prone to lung infections after becoming bedridden. If bedridden, it is important to frequently turn them over and pat their back to prevent the onset of lung infections.
After-effects of encephalitis
Some more serious types of encephalitis may leave sequelae. For example, common ones like herpes simplex viral encephalitis and epidemic encephalitis B. A minority of patients may suffer from certain degrees of sequelae, which typically include the following aspects. Firstly, some patients may experience secondary epileptic seizures, which present with loss of consciousness, limb convulsions, incontinence, and frothing at the mouth. These symptoms might require long-term oral medication for epilepsy. Secondly, another consequence of encephalitis is cognitive impairment in patients, characterized by significant reductions in computational ability, memory, and executive function. Additionally, some forms of encephalitis might leave patients with psychiatric symptoms, such as speaking incoherently.
What does a stroke cause?
Stroke primarily causes neurological deficits such as limb paralysis in patients. This paralysis is typically hemiplegic, where one side of the body lacks strength, the affected limbs cannot walk, and the upper limbs cannot be lifted. Stroke can also cause numbness in the limbs. Patients may experience reduced pain and temperature sensation on one side of the body, unable to feel pain or temperature. Additionally, stroke can lead to headaches and symptoms such as nausea and vomiting, commonly seen in hemorrhagic strokes, such as cerebral hemorrhage. Furthermore, strokes in specific brain areas like the frontal lobe, temporal lobe, and hippocampus can cause cognitive impairments. Patients become slow to react, have significantly reduced learning and memory capabilities, and their ability to perform daily activities and work is noticeably affected. Strokes can also cause unclear speech, where patients have difficulties in expressing themselves verbally and may even be unable to understand conversations.
Treatment of Cerebral Infarction
As society ages, the incidence of cerebral infarction is also increasingly higher, making rational treatment extremely important. Generally, the treatments for cerebral infarction include the following methods: The first point is intravenous thrombolysis, which is a very important treatment plan. If patients can reach the hospital within the thrombolysis time window and are assessed by a neurologist as having no contraindications, they can undergo intravenous thrombolysis treatment, from which many patients benefit. Second, with the advancement of medicine, some patients can also undergo interventional surgery for arterial thrombectomy. Third, the treatment for most patients mainly involves the use of antiplatelet drugs and statins. Additionally, medications that clear free radicals and protect brain cells are provided, along with scientifically-based rehabilitation training.
Does facial neuritis cause facial pain?
Facial neuritis is mainly caused by idiopathic facial nerve paralysis, which primarily manifests as paralysis of the facial muscles. Symptoms include deviation of the mouth, eyelid closure, lack of strength in opening the eyes, and shallowing of the nasolabial fold. Some patients' conditions are related to viral infections, which may cause facial pain. However, the pain is generally not very severe, and anti-viral medications can be used for treatment, which are somewhat effective. Additionally, active treatment of facial neuritis mainly involves the use of corticosteroids and is supported by the administration of B-group vitamins. Most patients, with timely and active treatment, have a relatively very good prognosis, with many experiencing no residual effects. (Please take medications under the guidance of a professional physician, do not self-medicate.)
Myasthenia gravis often co-occurs with which diseases?
Myasthenia gravis is a type of autoimmune disease of the nervous system, mainly caused by the production of abnormal antibodies in the body. These antibodies affect the acetylcholine receptors in the postsynaptic membrane, thereby impacting the transmission of nerve impulses at the neuromuscular junction. Being an autoimmune disease, myasthenia gravis usually coincides with the following conditions: The first major category is thymus diseases, with most patients experiencing thymic hyperplasia, and particularly, there may be cases of thymoma. If there is a thymoma, it is advised to undergo surgical treatment promptly. The second major category may involve hyperthyroidism, so it is essential to test thyroid function. Thirdly, some patients may also test positive for antinuclear antibodies, which requires careful differential diagnosis.
What should not be eaten in the case of myasthenia gravis?
Myasthenia gravis is an autoimmune disease of the nervous system, primarily due to dysfunction at the neuromuscular junction, leading to skeletal muscle fatigue. Symptoms include drooping eyelids, double vision, overall weakness, and even swallowing difficulties. Foods that should be avoided in myasthenia gravis mainly include certain medications, such as aminoglycoside antibiotics, which should not be taken orally by patients, as well as fluoroquinolone antibiotics. These antibiotics can exacerbate neuromuscular transmission disorders, potentially worsening the disease. Additionally, benzodiazepines, barbiturates, and some anti-arrhythmic drugs can also reduce muscle membrane excitability and should be avoided.
