For patients with dementia, it is recommended to take some cholinesterase inhibitors, which can increase the content of acetylcholine in the brain and have certain effects on improving cognitive functions. Additionally, consuming NMDA receptor antagonists can also help improve cognition. In terms of diet, it is advised that patients eat more foods rich in unsaturated fatty acids, such as fish, shrimp, and olive oil. It's also beneficial to consume plenty of fresh vegetables and fruits, which are rich in vitamin C and can help combat oxidative stress. Drinking more milk and eating foods rich in B vitamins, mainly whole grains, is also recommended. (Medication should be used under the guidance of a doctor.)

What is dementia called?

The commonly mentioned senile dementia, also known as Alzheimer's disease, is the most common type of dementia. Its incidence generally increases in people over the age of 65 and continues to increase with age. It is a degenerative disease, with risk factors including age and gender, usually higher in women than in men. It is also related to educational level, whether there has been trauma, genetics, thyroid function, exposure to toxic substances, as well as vascular factors. Diabetes and depression are also risk factors for senile dementia.

precursors of senile dementia

The diagnosis of senile dementia must first meet the diagnostic criteria for dementia, primarily characterized by impairment in multiple cognitive areas such as memory, language skills, executive function, and computational ability, and these impairments affect daily life; this is called senile dementia. Before dementia occurs, there are some precursory signs, mainly slight declines in memory. For example, patients might occasionally forget to bring keys when going out, or forget to turn off the stove while cooking. These mild memory impairments are some of the precursors to senile dementia. Additionally, there is a decline in learning ability, including the symptoms of learning new knowledge and mastering new skills; these declines are also precursors to senile dementia. Therefore, the precursors of senile dementia can primarily be summarized as a slight decline in memory function and some slight decline in learning ability.

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.

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.

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.
