    en.wikipedia.org/wiki/Vascular_dementia

    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]

    The brain volume decreases roughly 5% per decade after forty. It is currently unclear why brain volume decreases with age. However, a few causes may include cell death, decreased cell volume, and changes in synaptic structure.

  4. Dementia - Wikipedia

    Brain regions affected are similar to those that are affected by aging, and also by Alzheimer's disease. Regions showing loss of volume include the frontal, temporal, and parietal lobes, as well as the cerebellum, thalamus, and hippocampus. [86] This loss can be more notable, with greater cognitive impairments seen in those aged 65 years and older.

    [6] [7] Regional volume reduction is not uniform; some brain regions shrink at a rate of up to 1% per year, whereas others remain relatively stable until the end of the life-span. [8] The brain is very complex, and is composed of many different areas and types of tissue, or matter.

  6. Classic autism - Wikipedia

    en.wikipedia.org/wiki/Classic_autism

    Autism is caused by a combination of genetic and environmental factors, [6] with genetic factors thought to heavily predominate. [7] Controversies surrounded other proposed environmental causes; for example, the vaccine hypothesis, which although disproved, continues to hold sway in certain communities. [8] [9] After DSM-5/ICD-11 the term ...

    Finally, evidence for the recovery of brain volume with continued sobriety is supported by the improvement in neuropsychological performance. Compared to the control participants, abstinent alcoholic patients scored significantly better on tests measuring cognitive, sensory, and motor functions including abstract reasoning , memory ...

  9. Central diabetes insipidus - Wikipedia

    en.wikipedia.org/wiki/Central_diabetes_insipidus

    Central diabetes insipidus, recently renamed arginine vasopressin deficiency (AVP-D), [1] is a form of diabetes insipidus that is due to a lack of vasopressin (ADH) production in the brain. Vasopressin acts to increase the volume of blood (intravascularly), and decrease the volume of urine produced.
