The intellectual impairment in multi-infarct dementia sometimes involves only certain specific, limited cognitive functions, such as difficulties with calculation and naming. The general reasoning and judgment can remain intact for a considerable period of time, and they are often able to detect these impairments and actively seek medical attention or make efforts to compensate for them, hence the term “mesh-like dementia”. So, what are the prevention methods for reticular dementia? Here is a brief introduction. 1, the clinical manifestations of reticular dementia is not specific patients have a history of multiple ischemic stroke events cerebral infarction focal localization signs such as central facial and tongue palsy hemiparesis, hemianesthesia, hypertonia cone bundle sign pseudomyelination palsy hypersensitivity and urinary incontinence, etc. 2, mesh-like dementia MID can be acute onset, phased progression, intellectual impairment is often patchy deficits, mental activity disorders and vascular lesions damage the site and volume of brain tissue is directly related to cognitive dysfunction manifested as near memory and calculating power loss of expression indifference, anxiety, few words depression or euphoria can not perform familiar work and normal interaction, lost outside and do not recognize the door, wearing the wrong clothes and pants Eventually unable to take care of themselves. 3. Vascular dementia (VaD) is less impaired than reticular dementia in terms of time and place orientation short story immediate and delayed recall naming and retelling, and more impaired in terms of executive functions such as self-organization planning fine motor co-working. The clinical manifestations caused by different vascular lesions vary.
