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.

Late-stage symptoms of dementia

In the later stages of dementia, symptoms become very severe. Patients experience significant impairment in memory function, forgetting not only recent events but also events from the past. Additionally, patients show obvious impairments in visuospatial abilities, having trouble locating the bathroom in their own home, and often getting lost when they go out. There is also a noticeable change in behavior, with patients exhibiting aggression, cursing, and inappropriate actions like urinating or defecating in random places. Some patients may experience recurrent visual and auditory hallucinations. As the disease progresses, elderly patients may eventually become bedridden for life, not interacting with anyone, remaining silent, and refusing to eat. They ultimately may die from complications such as lung infections, urinary tract infections, malnutrition, and bedsores. Therefore, the symptoms of dementia in its later stages are quite severe, with cognitive impairments, abnormal mental and behavioral symptoms, and various infections all posing serious threats to the health of the elderly.

What to do about senile dementia?

When dementia occurs in the elderly, there is a noticeable decline in cognitive function. Initially, it is important to identify the cause of the dementia; some cerebrovascular diseases can also cause dementia. For example, cerebral infarction in certain specific areas of the brain can lead to dementia if it affects the intelligence center. For dementia caused by these reasons, it is recommended to treat with antithrombotic medications, including antiplatelet aggregation drugs and brain cell protective medications. Additionally, if the dementia is caused by Alzheimer's disease, close care is needed to prevent incidents like the patient getting lost. It is advisable to write contact numbers in the pockets of their clothes and administer acetylcholinesterase inhibitors to increase the levels of acetylcholine in the brain, which can improve cognitive function to a certain extent. (Note: This answer is for reference only. Medication should be prescribed and managed under the guidance of a professional physician, and self-medication should be avoided.)

Is senile dementia hereditary?

The disease referred to as dementia mainly refers to Alzheimer's disease. Only a very small number of cases are hereditary, where patients have a certain family history caused by genetic mutations, thus having some hereditary traits. However, the vast majority of Alzheimer's cases are sporadic, unrelated to genetic mutations, and these sporadic cases are not hereditary, so there is no need to worry about transmitting it to offspring. Nevertheless, it is important to note that, with the progression of population aging, the incidence of this disease remains relatively high, especially for those over the age of 65, who need to pay close attention to this disease. If a patient exhibits a decline in memory function, do not assume it is just forgetfulness; it is crucial to visit a hospital for diagnosis and timely treatment.

What is the full name of dementia?

Senile dementia mainly refers to Alzheimer's disease, a condition with a relatively high incidence rate among the elderly population, and it is the most common neurodegenerative disease. The specific causes and mechanisms of this disease are not particularly clear. Under the influence of various factors, degeneration and death of the temporal lobe, hippocampus, and neurons occur, leading to a series of clinical manifestations. Initially, it mainly manifests as a decline in recent memory function, often forgetting recent events. As the disease progresses, there is a decline in calculating ability and judgment, significant spatial dysfunction, personality changes, and psychiatric symptoms.
