Dementia may occur when neurodegenerative and cerebrovascular pathologies are mixed, as in susceptible elderly people (75 years and older). [2] [5] Cognitive decline can be traced back to occurrence of successive strokes. [4] ICD-11 lists vascular dementia as dementia due to cerebrovascular disease. [1]
For example, muscle inflammation due to dermatomyositis may cause AST>ALT. This is a good reminder that AST and ALT are not good measures of liver function when other sources may influence AST and/or ALT, because they do not reliably reflect the synthetic ability of the liver, and they may come from tissues other than liver (such as muscle).

The deadline for the United States to begin using ICD-10-CM for diagnosis coding and Procedure Coding System ICD-10-PCS for inpatient hospital procedure coding was set at October 1, 2015, [51] [52] a year later than the previous 2014 deadline. [53] Before the 2014 deadline, the previous deadline had been a year before that on October 1, 2013.
Blood tests, cerebrospinal fluid examination by lumbar puncture (also known as spinal tap), brain imaging studies, electroencephalography (EEG), neuropsychological testing and similar diagnostic studies may be used to differentiate the various causes of encephalopathy. [citation needed] Diagnosis is frequently clinical.
Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
Other common causes of chronic organic brain syndrome sometimes listed are the various types of dementia, which result from permanent brain damage due to strokes, [7] Alzheimer's disease, or other damaging causes which are irreversible. Amnestic pertains to amnesia and is the impairment in ability to learn or recall new information, or recall ...

Binswanger's disease is a type of subcortical vascular dementia caused by white matter atrophy to the brain. However, white matter atrophy alone is not sufficient for this disease; evidence of subcortical dementia is also necessary.
