Introduction
Cognitive impairment is a general term for impaired cognitive function, mainly characterized by memory decline, difficulty concentrating, language expression difficulties, reduced executive function, and abnormalities in visuospatial abilities. Cognitive impairment gradually affects the ability to perform activities of daily living. With targeted cognitive training, regular作息 (daily routines), and a healthy diet, the progression of symptoms can be delayed to some extent, thereby improving quality of life.
Cognitive impairment is a general term for impaired cognitive function, mainly manifested as memory decline, difficulty concentrating, language expression difficulties, reduced executive function, and abnormal visuospatial abilities. A detailed analysis is as follows:
1. Memory decline: Patients often experience deterioration in short-term memory, struggling to remember recent events or conversations—such as repeatedly asking the same question or misplacing everyday items. Long-term memory may remain relatively intact, allowing recall of distant past events. However, as the condition progresses, long-term memory may also become impaired.
2. Difficulty concentrating: Patients find it hard to focus on a single task, are easily distracted by external stimuli, frequently lose concentration, and often fail to complete tasks. For example, they may be unable to concentrate while reading, struggle to follow others' train of thought during conversations, and require excessive time to complete simple household chores.
3. Language expression difficulties: Patients may use inappropriate words or speak in disjointed sentences, failing to express their thoughts clearly. During conversations, they often struggle to find the right words, hesitate frequently, or even forget common vocabulary. In severe cases, normal conversation may become impossible.
4. Reduced executive function: Patients have difficulty planning, organizing, and completing daily tasks—such as creating a reasonable shopping list or following steps to cook a meal. They may show indecisiveness, poor judgment, and an inability to make correct choices even regarding simple matters.
5. Visuospatial abnormalities: Patients may lose their sense of direction, becoming disoriented even in familiar environments. They may be unable to accurately judge object positions—such as difficulty inserting arms into sleeves when dressing, inability to align objects properly when placing them, and, in severe cases, compromised walking safety.
Cognitive impairment progressively affects the ability to perform daily living activities independently. Targeted cognitive training, regular sleep patterns, and a healthy diet can help slow symptom progression and improve quality of life to some extent.
