Dementia is a symptom of many diseases. For example, primary degenerative dementia includes Alzheimer’s disease, Lewy body dementia, Pick’s disease, and multisystem atrophy. Vascular dementia, on the other hand, is the result of multiple infarcts, subcortical atherosclerotic encephalopathy, and intracranial hemorrhage. Other causes of dementia include cranial trauma, intracranial occupying lesions, intracranial infections, nutritional deficiencies, metabolic and endocrine disorders, alcoholism, gas poisoning, and mixed dementia. Many of these conditions can lead to dementia. Therefore, if people have the first signs or manifestations of dementia, they should go to a well-conditioned cause as soon as possible in order to identify the cause of dementia and further prescribe the right medicine. Like other diseases, dementia must be treated and intervened early, i.e. the earlier the treatment, the better the effect will be. Information shows that early treatment can improve the quality of life of patients and slow down the development of dementia. How to recognize the early signs of dementia is a major concern. The following are ten early signs of dementia: 1. Memory loss, especially forgetfulness of recent events, is the most common symptom of early dementia. Patients can’t remember what happened that day, they can’t remember what they just did or what they said, they can’t remember the names of familiar people, they forget appointments, they forget where they put their valuables. 2. Difficulty performing familiar tasks Patients with dementia have difficulty performing daily household tasks. For example, the patient may not know the order of dressing or the steps of cooking a meal. 3. Language impairment Patients with dementia may often forget simple words or replace them with words that are not commonly used, resulting in words that are incomprehensible; they may not be able to name everyday objects (such as watches); and the amount of spoken language decreases. 4.Decreased calculation power often miscalculates and pays wrongly. 5.Time and place orientation disorder forget what day of the week it is, can’t remember the specific year, month and day, and can get lost in familiar places. 6, spatial orientation disorder when wearing a jacket hands can not reach into the sleeve, lost or do not recognize the door, can not draw simple geometric figures. 7. Impaired judgment and difficulty in abstract thinking Patients with dementia are slow to respond and have difficulty following the thoughts of others when talking. 8, emotional or behavioral changes in patients with dementia can become extremely unstable, depressed, indifferent or agitated, anxious, and inattentive than before. 9.Personality changePatients with dementia may behave differently than before the disease, such as suspecting family members of stealing their money or hiding something of little value. 10. Loss of interest The person with dementia may become passive, lack initiative, sit in front of the TV for long periods of time or be lethargic all day, and lose interest in previous hobbies. If you or the person you care for has any of these symptoms, you should seek prompt medical attention. A diagnosis of dementia, for example, can lead to timely help. The earlier the diagnosis is made, the better the treatment and the better it is for making reasonable arrangements and plans with your family for the rest of your life.
