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.

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.

symptoms of dementia in the elderly

The symptoms of dementia mainly include: First, impaired memory function, where the patient’s memory loss is very noticeable. Initially, they may not remember recent events, and as the disease progresses, they may not remember past events, such as forgetting how many children they have or their children’s names. Second, it mainly involves symptoms of impairment in other cognitive areas, such as visual spatial dysfunction, manifesting as not being able to find the bathroom at home, getting lost after going out, and not being able to find the way back home. Additionally, the patient's ability to understand, calculate, and judge will also be significantly impaired, and they cannot master previously learned knowledge and skills. Third, in the late stages, some psychiatric symptoms appear, including visual and auditory hallucinations, and agitated behaviors such as hitting and cursing. Additionally, the patient may also experience some physical weakness, muscle atrophy, and incontinence.

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.

What can be done about senile dementia?

Once a patient is diagnosed with dementia, it is crucial to promptly visit a hospital for treatment. The doctor will conduct some auxiliary examinations based on the patient's medical history to rule out other diseases. If the diagnosis confirms dementia, firstly, family members must pay attention to care. The living abilities of patients with dementia decline significantly, and they may experience wandering, thus enhancing caregiving to prevent any accidents in the elderly; Secondly, it is essential to encourage the patient to engage in physical activities. Exercise can slow down the progression of aging and delay the further deterioration of dementia; Thirdly, it is vital to enhance communication for the patient, encouraging them to converse more with others, as interaction can slow down the progression of dementia; Fourthly, some specific medications should be administered for treatment. These drugs mainly include acetylcholinesterase inhibitors and NMDA receptor antagonists, which current research confirms can alleviate certain symptoms of dementia.

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.
