Dementia
Alzheimer's disease is also called dementia.
Alzheimer's disease, also known as dementia in the elderly, was first identified abroad and thus named after the discoverer, Alzheimer. It is one of the most common neurodegenerative diseases in neurology, with a very high incidence among people over 65 in China and worldwide. The disease mainly affects patients' cognitive functions. Initially, patients do not meet the criteria for dementia and primarily exhibit a decline in memory. As the disease progresses, the decline in memory worsens, and patients begin to forget both recent and past events. Additionally, they may experience impairments in visuospatial abilities, judgment, comprehension, and learning capabilities. In the later stages, psychiatric symptoms and personality changes may appear, such as visual hallucinations, shouting, and gesturing wildly, among various other clinical manifestations.
What is the greatest fear in Alzheimer's disease?
Dementia in the elderly is a common neurodegenerative disease worldwide. It is a clinical syndrome caused by the irreversible death of brain neurons due to various factors. Initially, the main symptom in patients is impaired memory function, which at this stage does not significantly affect work and life, and is not overly concerning. As the disease progresses, the cognitive functions of the elderly, including visuospatial skills, calculation abilities, and executive functions, are notably impaired. Changes in personality and behavior also occur. What is most feared in dementia? It is particularly concerning when elderly individuals go out on their own and then cannot find their way home, leading to situations where they may become lost. If the elderly are unable to find adequate food outdoors, or if the weather is too cold or too hot, their life safety can be severely threatened. Additionally, dementia patients might inadvertently turn on the gas at home and forget to turn it off, which can easily lead to accidents. These are the most feared incidents related to dementia in the elderly.
Can senile dementia be cured?
Dementia in the elderly is a clinical syndrome caused by the irreversible death of neurons. So far, the mechanism of the disease is not particularly clear, making it very difficult to cure dementia completely. However, there are some corresponding treatment methods that can delay the progression of the disease and improve the quality of life of patients as much as possible. These treatments mainly include exercise therapy, which involves getting patients to participate in appropriate physical activities that can promote cognitive development. In addition, letting patients listen to music more often, interact more with others, and continue learning can also delay the progression of aging. Furthermore, there are some medications that can improve the symptoms of dementia. Currently, the most commonly used worldwide are acetylcholinesterase inhibitors, which can increase the levels of acetylcholine and thereby improve cognitive function to some extent and slow the progression of the disease. Additionally, if elderly individuals exhibit some psychiatric symptoms, they can also be given some atypical antipsychotic medications to alleviate the condition.
Is senile dementia hereditary?
Dementia primarily refers to Alzheimer's disease, which mainly has two types: The first type is sporadic Alzheimer's disease, which does not have a clear familial history. It is caused by the degeneration and death of neurons due to various reasons, leading to certain clinical symptoms. This type of sporadic dementia does not have a genetic predisposition. The other type of dementia has a clear family history, where patients typically exhibit mutations in the APP gene, leading to increased secretion, which in turn causes the death of neurons and results in the symptoms of dementia. This familial type of dementia has a genetic predisposition. Dementia is a common condition in neurology and is the most common neurodegenerative disease. Currently, there are no effective treatments available. Family members must pay attention to caregiving, and patients can take cholinesterase inhibitors, which can improve symptoms to a certain extent.
Symptoms of dementia in the elderly
Dementia in the elderly is medically known as Alzheimer's disease, which is categorized into mild, moderate, and severe stages. The clinical manifestations vary with the severity of the disease. Mild dementia primarily presents as memory impairment, starting with a decline in short-term memory, where patients often forget daily activities. For instance, they might forget the way home when they go out, forget to add salt when cooking, or forget to turn off the stove. Patients may also exhibit personality disorders, such as neglecting personal hygiene or not wanting to bathe. As the disease progresses to moderate dementia, besides worsening memory impairment, the patient's ability to work, learn new knowledge, and communicate with others significantly diminishes. There is a notable decline in previously acquired knowledge and skills, such as judgment and calculation abilities. They may also experience aphasia, apraxia, agnosia, and some patients may exhibit significant behavioral and psychological abnormalities. With further progression to severe dementia, patients may become emotionally detached, exhibit unpredictable crying or laughing, fail to recognize family members, lose verbal abilities, and even become unable to perform simple tasks such as dressing or eating. They may spend their days in bed, not speaking, and gradually lose contact with the outside world, ultimately leading to death.
How long is the lifespan of someone with Alzheimer's?
The causes of dementia in the elderly can be varied, with many diseases such as Alzheimer's disease, Parkinson's disease, and vascular dementia, all leading to senile dementia. Therefore, how long one lives may require specific analysis. If the dementia is due to cerebrovascular factors, the lifespan of the individual may be closely related to the primary disease, i.e., cerebrovascular disease. Dementia caused by Alzheimer's disease progresses with the disease and affects the patient's lifespan. In its advanced stages, when the patient can no longer take care of themselves, complications such as lung infections can further impact their lifespan. There are also other factors, which need to be assessed based on the evaluation of the disease.
Determination of Senile Dementia
The assessment of dementia primarily encompasses three aspects: The first aspect mainly involves relevant neurological scales, which can scientifically and effectively measure the cognitive functions of elderly patients. These scales include the MSE (Mini-Mental State Examination) and the MoCA (Montreal Cognitive Assessment). The second aspect of the assessment involves some imaging tests, mainly cranial MRI scans. Cranial MRI can determine if there is brain atrophy in the elderly and examine for any related lesions in the temporal lobes and hippocampi. The third major aspect involves the analysis of cerebrospinal fluid, assessing the levels of amyloid proteins, which also play an important role in the assessment of dementia. In summary, the assessment of dementia primarily involves evaluations using neurological scales, cranial MRI, and cerebrospinal fluid analysis.
How is Alzheimer's disease treated?
Senile dementia, also known as Alzheimer's disease, is the most common neurodegenerative disease worldwide. The pathogenesis of this disease is not particularly clear so far and may be related to genetic and environmental factors. Multiple factors act on neurons causing irreversible and progressive death of neuronal cells. Currently, the treatment of this disease mainly includes two aspects. The first aspect is general treatment, mainly including family care. Family members must pay attention to the care of the patient, prevent the patient from accidentally wandering off, prevent the patient from falling, and prevent some accidents that cause injuries. In addition, it is important for the patient to listen to music, interact with others, and exercise more, all of which can delay the progression of senile dementia. The second aspect is pharmacological treatment, mainly using drugs that inhibit the reduction of acetylcholine. These drugs can increase the content of acetylcholine and improve the cognitive functions of patients to a certain extent, but so far, these treatments cannot reverse senile dementia.
early signs of dementia
Dementia in the elderly, mainly referring to Alzheimer's disease, is primarily characterized by a significant decline in the patient's memory and learning abilities. Of course, there are some prodromal symptoms before the onset of dementia. For example, patients might show no clinical signs of cognitive impairment or only display very slight memory decline. Patients might exhibit mild impairment in memory, a decrease in the ability to learn and retain new information, and mild impairments in other cognitive areas such as attention, executive function, language skills, and visuospatial abilities. However, these impairments are very slight and can go unnoticed by family members. Moreover, these mild impairments do not affect the patient's basic daily life abilities and do not reach the level of dementia. Patients can live independently and manage their routine daily tasks, which are mainly some of the early signs of dementia.
Causes of Alzheimer's Disease in the Elderly
The causes of dementia in the elderly are not currently completely clear. Dementia in the elderly is mainly divided into familial and sporadic types. Familial dementia shows autosomal dominant inheritance, which is caused by a gene mutation on chromosome 21 leading to the accumulation of some toxins, resulting in the death of neurons and causing dementia fundamentally due to genetic mutations. However, most cases of dementia are sporadic and do not have a clear family history. The mechanisms and reasons for disease onset are not particularly clear. Some believe that abnormalities in cerebral vascular function may lead to neuronal cell functional disorders, resulting in decreased ability to clear certain cell toxins, thus leading to neuronal apoptosis and death, and consequently impaired cognitive functions. In addition, factors such as oxidative stress, inflammatory mechanisms, excessive fatigue, and emergency stress may also cause cell death. Overall, the causes of dementia in the elderly are not particularly clear.
