Dementia
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.
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.
probability of senile dementia
Dementia primarily refers to Alzheimer's disease, which has a relatively high incidence rate. In China, among the elderly population over 65 years old, approximately 3% to 7% are affected; this rate can rise to over 20% among those over 85 years old. Suffering from dementia places a heavy burden on the patient, their family, and society. Initially, patients with dementia will experience a decline in memory function. As the condition progresses, there will be a decline in various cognitive functions. For example, spatial dysfunction might occur, such as getting lost on the way home, personality changes, and the emergence of psychiatric symptoms and other clinical manifestations.
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 to do about senile dementia?
For patients with dementia, if the diagnosis is confirmed, the recommended treatment is as follows: First, it is very important to pay attention to nursing care. Patients with dementia often get lost, which can lead to a series of dangers, so it is necessary to take good care of them to prevent getting lost. Secondly, for the improvement of cognitive functions, it is recommended to use some cholinesterase inhibitors, which can increase the level of acetylcholine in the brain and improve the patient's cognitive functions to a certain extent. Third, symptomatic treatment should also be provided. Since patients with dementia often exhibit psychiatric symptoms, such as visual and auditory hallucinations, appropriate antipsychotic medications can be used for treatment. (Please use medication under the guidance of a professional physician.)
Methods for Examining Dementia in the Elderly
The examination of dementia mainly includes the following aspects. First, it is to determine whether the patient has cognitive impairment, because in the early stages of dementia this impairment is often mild, primarily in recent memory, with other aspects not yet obvious. Early screening can use some cognitive evaluation scales, such as the Mini-Mental State Examination or the Montreal Cognitive Assessment, chosen according to the patient's cultural level. Second, imaging examination, commonly using brain MRI, can reveal significant signs of dementia such as deepened brain sulci, narrowed gyri, and widened lateral fissures, indicating brain atrophy. Third, genetic testing for the APOE gene, which may be related to dementia. Possession of this gene may increase the likelihood of developing dementia in the future, serving as an auxiliary diagnostic measure.
Causes of Dementia
At present, the specific causes and mechanisms of Alzheimer's disease are not very clear, but they are mainly divided into two categories. The first category is hereditary, where some Alzheimer's disease cases have a clear family history and involve some genetic mutations. These genetic mutations lead to the deposition of abnormal proteins within neurons, causing irreversible neuronal death, which is the main reason for familial Alzheimer’s disease. The second category is sporadic Alzheimer’s disease, for which no clear pathogenesis has been identified. Research suggests that factors such as oxidative stress, trauma, cerebrovascular disease, cerebral ischemia, and other factors, including metabolic conditions leading to dementia, are related to the occurrence of sporadic Alzheimer's disease. Therefore, the causes of Alzheimer’s disease include two main categories: the first is caused by genetic mutations, and the second is caused by various adverse factors leading to neuronal death.
Is spinal bifida prone to dementia?
Spina bifida is a common congenital malformation caused by incomplete closure of the vertebral canal during embryonic development. If the spina bifida is occult, it does not affect anything and does not cause dementia. If it is overt spina bifida, it can be diagnosed through physical examination, and confirmed with radiographic examination, CT, or MRI. Typically, the patient has a swelling along the midline of the back, which grows as they age. The cystic tension increases when the child cries, and may be accompanied by varying degrees of flaccid paralysis of the lower limbs and incontinence. Occult spina bifida generally has no symptoms and does not require intervention. However, overt spina bifida is best treated surgically, or if the occult spina bifida is accompanied by spinal cord tethering, then surgical treatment is recommended as it would be for all cases of overt spina bifida. In cases where the cyst wall is very thin and ruptured, emergency surgery is necessary and can be curative. For other cases, surgery within one to three months is optimal to prevent aggravation of the condition due to cyst rupture. Generally, adult patients with stable conditions in recent years may not need surgery.
How is dementia diagnosed in the elderly?
Alzheimer's disease is a degenerative disease of the nervous system. The diagnosis of this disease mainly relies on the clinical manifestations of the patient, as well as some corresponding scales and some corresponding imaging examinations. In terms of examinations, it is necessary to check some neurofunctional scales, mainly cognitive function scales, common scales include some MMSE scales, and some MoCA scales. These scales are very important for diagnosing this disease. In addition, some imaging examinations need to be improved, mainly including cranial magnetic resonance imaging examinations. Cranial MRI can reveal atrophy in the patient's temporal lobe, hippocampus, and other areas, which also have an important reference value for the diagnosis of the disease. Moreover, an electroencephalogram can be performed to see some mild abnormalities, and lumbar puncture tests can also reveal some abnormally increased protein deposits.
