Does posterior cortical atrophy progress into general dementia? Please, need some answers?

Does posterior cortical atrophy progress into general dementia? Please, need some answers?

Yes.: It is not known whether PCA is a variant of Alzheimer's or not as the symptoms are very similar.In PCA the atrophy starts in the back of the brain rather than a global atrophy. ...Read more

Atrophy (Definition)

Atrophy usually refers to the skin-as you get older or if you have had alot of sun in the past-the dermis (that is the layer below the top layer which is called the epidermis) gets thinner and the skin looks more wrinked. Muscles and fat can also get thinner -this is another form of atrophy. Even the top layer gets thinner ...Read more

Can CT see brain atrophy from alzheimer's or dementia?

Can CT see brain atrophy from alzheimer's or dementia?

If advanced, yes: If alzheimer's or other dementia is far enough advanced, then ct can show cortical atrophy and enlarged ventricles. However, functional brain changes can be going on for a long time before anatomical changes show up. ...Read more

Are there new tests for dementia being developed for boomers who might have 'partied' hard?

Are there new tests for dementia being developed for boomers who might have 'partied' hard?

Heavy alcohol: Consumption has immediate & long-term negative effects on the brain. Heavy drinking accelerates brain shrinkage leading to cognitive decline. In contrast to alzheimer’s alcohol's effects on the brain may be reversible. Atrophy (brain shrinkage) decreases after abstinence from alcohol. Currently, no strong evidence suggests that alcohol use influences risk of developing ad, more research isneeded. ...Read more

Would dementia show up on MRI or cat scan?

Would dementia show up on MRI or cat scan?

Not necessarily: Mri and cat scans show anatomical brain changes only, not functional ones. If a dementia is far enough advanced to change brain structures, it would "show up" on these scans. However, there may be a long decline in brain function before that point is reached. There are functional scans which might detect changes before anatomic anomalies can be seen. A normal MRI does not "rule out" dementia. ...Read more

Does an MRI w/contast show if someone in 80's has dementia& would sleeping meds & chemo affect impressions of that test?

Does an MRI w/contast show if someone in 80's has dementia& would sleeping meds & chemo affect impressions of that test?

MRI may be useful: There are different types of dementia. Mri may show certain areas of brain atrophy attributable to certain dementia. Mri may show certain tissue/location involvement attributable to certain dementia. Vascular dementia is from having prior strokes and MRI may show this. Chemotherapy may affect brain tissue and can be confounding factors in MRI interpretation. ...Read more

Can dementia be seen with ct? If so what changes would be evident?

Can dementia be seen with ct? If so what changes would be evident?

Very advanced, yes: A very advanced dementia would likely show cerebral cortical atrophy and enlarged ventricles. Earlier in the process you might not see anything at all, though -- because a ct scan registers only anatomic changes, not functional or physiological ones. These may go on for a long time, and could also result in symptoms -- long before anatomic changes show up on ct. ...Read more

My doctor thinks my grandma might have temporal frontal dementia. Wants more info to confirm, but I am worried. What exactly is it? How is it treated?

My doctor thinks my grandma might have temporal frontal dementia. Wants more info to confirm, but I am worried. What exactly is it? How is it treated?

There are 3 types: Named for the brain areas that are affected, the frontal and temporal lobes, there are several different variants of this type of dementia. Some of these types of dementia have prominent problems with words - either slowly losing the ability to speak or losing the ability to makes sense when one talks. There is an impulsive, disinhibited personality variant also. ...Read more

Why do I have symptoms of dementia but a CT scan showed nothing?

Why do I have symptoms of dementia but a CT scan showed nothing?

Not sensitive: Ct is insensitive and nonspecific for dementia. Mri and pet are better, but clinical evaluation by a neurologist is most important. ...Read more

Would a CT with and without contrast show any evidence of Alzheimer's or dementia?

Yes,: the CT may show a particular pattern of atrophy that can be associated with Alzheimer's . ...Read more
