More than 145 monogenic diseases have been identified that cause dementia with onset in childhood. Examples include lysosomal disorders such as Sanfilippo syndrome, Niemann-Pick disease type C and Neuronal Ceroid Lipofuscinoses (NCLs or Batten Disease), some mitochondrial diseases such as Leigh syndrome and peroxisomal disorders such as X ...
An example of how the liability threshold works can be seen in individuals with cleft lip and palate. Cleft lip and palate is a birth defect in which an infant is born with unfused lip and palate tissues. An individual with cleft lip and palate can have unaffected parents who do not seem to have a family history of the disorder. [citation needed]
Two unaffected people who each carry one copy of the mutated gene have a 25% risk with each pregnancy of having a child affected by the disorder. Examples of this type of disorder are albinism, medium-chain acyl-CoA dehydrogenase deficiency, cystic fibrosis, sickle cell disease, Tay–Sachs disease, Niemann–Pick disease, spinal muscular ...
Neurocognitive disorders include delirium, mild neurocognitive disorders, and major neurocognitive disorder (also known as dementia). They are defined by deficits in cognitive ability that are acquired (as opposed to developmental), typically represent decline, and may have an underlying brain pathology. [ 1 ]
Psychogenic polydipsia caused by psychiatric disorders—oftentimes schizophrenia—is frequently accompanied by the sensation of dry mouth. Some conditions with polydipsia as a symptom are non-psychogenic (e.g., early Type 2 diabetes , primary hyperaldosteronism , and zinc deficiency , and some forms of diabetes insipidus ).
Research has shown that many conditions are polygenic meaning there are multiple defective genes rather than only one that is responsible for a disorder, and these genes may also be pleiotropic meaning that they cause multiple disorders, not just one. [28] Schizophrenia and Alzheimer's are both examples of hereditary mental disorders. When ...
