 Meaning "deprived of mind," dementia is a serious loss of cognitive ability in a previously unimpaired person, beyond what might be expected from normal aging. Alzheimer's disease – also called Alzheimer disease, Senile Dementia of the Alzheimer Type (SDAT) or simply Alzheimer's – is the most common form of dementia. Meaning "deprived of mind," dementia is a serious loss of cognitive ability in a previously unimpaired person, beyond what might be expected from normal aging.

-Recent evidence suggests that infectious agents need serious investigation as potentially important factors that contribute to the progression, complexity and severity of Alzheimer's.(({{pubmed>long:18487850}})) Perhaps the most striking of this evidence is that amyloid-beta, the protein which builds up in the brains of Alzheimer's patients, is an antimicrobial petide. +Recent evidence suggests that infectious agents need serious investigation as potentially important factors that contribute to the progression, complexity and severity of Alzheimer's.(({{pmid>long:18487850}})) Perhaps the most striking of this evidence is that amyloid-beta, the protein which builds up in the brains of Alzheimer's patients, is an antimicrobial petide.

-Physicians use the diagnosis of mild cognitive impairment (MCI) to predict which patients have the highest risk of Alzheimer's. Although the rate at which patients go on to develop probable Alzheimer’s disease is relatively high – approximately 10-15% per year(({{pubmed>long:14732621}})) – the criteria for diagnosis of MCI excludes a lot of patients. In order to be given a diagnosis of MCI, patients must be "in good health," have "no significant cerebrovascular disease," and be between 55 and 90.(({{pubmed>long:14732621}})) These criteria rule out a number of patients sick with chronic disease. In fact, most patients with chronic disease report some level of cognitive dysfunction and would otherwise easily meet the other criteria for MCI. Furthermore, normal cognitive performance is expected to decline as people age; also, people over 90 are ineligible to be diagnosed with MCI, because any memory loss over that age is expected.+Physicians use the diagnosis of mild cognitive impairment (MCI) to predict which patients have the highest risk of Alzheimer's.

 In the clinical setting, Alzheimer's disease is usually diagnosed from the patient history, collateral history from relatives, and clinical observations, based on the presence of characteristic neurological and neuropsychological features and the absence of alternative conditions. Advanced medical imaging with computed tomography (CT) or magnetic resonance imaging (MRI), and with single photon emission computed tomography (SPECT) or positron emission tomography (PET) can be used to help exclude other cerebral pathology or subtypes of dementia. Definitive diagnosis of AD requires histopathologic examination, which is rarely done in life.  In the clinical setting, Alzheimer's disease is usually diagnosed from the patient history, collateral history from relatives, and clinical observations, based on the presence of characteristic neurological and neuropsychological features and the absence of alternative conditions.

 CONCLUSIONS/SIGNIFICANCE: Our results indicate that suppression of VDR disrupts LVSCC-A1C and NGF production. In addition, when VDR is suppressed, neurons could be vulnerable to aging and neurodegeneration, and when combined with Aβ toxicity, it is possible to explain some of the events that occur during neurodegeneration. CONCLUSIONS/SIGNIFICANCE: Our results indicate that suppression of VDR disrupts LVSCC-A1C and NGF production.
