Intracerebroventricular injection has been used to inject drugs that induce a diseased state to create animal models for a variety of diseases. Of these, Alzheimer's disease (AD) animal models are heavily represented in the literature. ICV injection of Streptozotocin has been used to create a metabolic model of Alzheimer's disease. This ...
Alzheimer's disease is a progressive neurodegenerative disorder associated with aging, which occurs both sporadically (the most common form of diagnosis) or due to familial passed mutations in genes associated with Alzheimer's pathology. [1] [2] Common symptoms associated with Alzheimer's disease include: memory loss, confusion, and mood ...
Pseudodementia can develop in a wide range of neuropsychiatric disease such as depression, schizophrenia and other psychosis, mania, dissociative disorders, and conversion disorders. The presentations of pseudodementia may mimic organic dementia, but are essentially reversible on treatment and doesn't lead to actual brain degeneration. However ...
Dementia is a general term for a decline in mental ability severe enough to interfere with daily life, according to the Alzheimer’s Association. Alzheimer’s is a specific disease that is the ...
Other types of dementia and cognitive conditions are many times misdiagnosed as Alzheimer’s disease. Researchers have identified another memory-loss condition called Limbic-predominant Amnestic ...
Progeroid syndromes (PS) are a group of rare genetic disorders that mimic physiological aging, making affected individuals appear to be older than they are. [1] [2] The term progeroid syndrome does not necessarily imply progeria (Hutchinson–Gilford progeria syndrome), which is a specific type of progeroid syndrome.
“Alzheimer’s disease has a long pre-symptomatic period; Alzheimer’s-related changes take place in the brain 10, 15, even 20 years before the onset of memory and thinking symptoms.
Posterior cortical atrophy (PCA), also called Benson's syndrome, is a rare form of dementia which is considered a visual variant or an atypical variant of Alzheimer's disease (AD). [ 1 ] [ 2 ] [ 3 ] The disease causes atrophy of the posterior part of the cerebral cortex , resulting in the progressive disruption of complex visual processing . [ 4 ]
