What does diffuse cortical atrophy mean?
Table of Contents
Overview. Brain atrophy — or cerebral atrophy — is the loss of brain cells called neurons. Atrophy also destroys the connections that help the cells communicate. It can be a result of many different diseases that damage the brain, including stroke and Alzheimer’s disease.
How long can you live with posterior cortical atrophy?

Life expectancy after PCA diagnosis is thought to be similar (8-12 years) to individuals affected with Alzheimer’s disease.
What are the symptoms of cerebral atrophy?
What Are Cerebral Atrophy Symptoms?
- Loss of reasoning ability.
- Disorientation.
- Difficulty with communication, whether vocally or in writing.
- Memory loss.
- Declines in reading comprehension.
- Onset of learning disabilities.
What are the symptoms of subcortical dementia?
Clinically subcortical dementia usually is seen with features like slowness of mental processing, forgetfulness, impaired cognition, lack of initiative-apathy, depressive symptoms (such as anhedonia, negative thoughts, loss of self-esteem and dysphoria), loss of social skills along with extrapyramidal features like …

Does cortical atrophy cause Alzheimer’s?
Posterior cortical atrophy (PCA), also known as Benson’s syndrome, is a rare degenerative condition in which damage occurs at the back (posterior region) of the brain. In the vast majority of people, the cause of PCA is Alzheimer’s disease.
What is cortical atrophy caused by?
Posterior cortical atrophy is most commonly due to Alzheimer’s disease (over 80%) but may be due to other neurological conditions, such as Lewy body dementia or corticobasal degeneration.
Is cortical atrophy normal?
Some degree of atrophy and subsequent brain shrinkage is common with old age, even in people who are cognitively healthy. However, this atrophy is accelerated in people with mild cognitive impairment and even faster in those who ultimately progress from mild cognitive impairment to Alzheimer’s disease.
How is brain atrophy treated?
There is no specific treatment or cure for cerebral atrophy. Some symptoms of underlying causes can be managed and treated. Controlling blood pressure and eating a healthy, balanced diet is advised. Some research suggests that physical exercise may slow the speed of atrophy.
Is brain shrinkage serious?
This loss may be the result of an injury, infection, or underlying health condition. Mild cases of brain atrophy may have little effect on daily functioning. However, brain atrophy can sometimes lead to symptoms such as seizures, aphasia, and dementia. Severe damage can be life threatening.
Does brain atrophy lead to dementia?
There’s a connection between brain atrophy and dementia. Specifically, dementia causes extreme brain atrophy. Dementia is a general term that describes severe thinking problems that interfere with daily life. The most common type of dementia is Alzheimer’s disease.
Is PCA a form of dementia?
Posterior cortical atrophy (PCA) is a rare form of dementia that usually begins by affecting a person’s vision. It is also known as Benson’s syndrome.
What are the stages of PCA?
Share this post
- Stage 1. No impairment (normal function)
- Stage 2. Very mild cognitive decline. – Difficulties with reading and writing.
- Stage 3. Mild cognitive decline.
- Stage 4. Moderate cognitive decline.
- Stage 5. Moderately severe cognitive decline.
- Stage 6. Severe cognitive decline.
- Stage 7. Very severe cognitive decline.
Is cortical demyelination a major cause of cortical atrophy?
These findings confirm the presence of significant cortical atrophy in this model. We conclude that localised cortical demyelination is not responsible for the major part of the atrophy observed and that cortical thinning is largely due to more diffuse or more remote factors.
What are the signs and symptoms of cortical atrophy?
Common symptoms include difficulties with reading, judging distances, and recognizing objects and familiar faces. This condition may eventually cause your memory and thinking abilities (cognitive skills) to decline. Posterior cortical atrophy may be due to Alzheimer’s disease, Lewy body dementia or other neurological conditions.
What is the pathophysiology of cortical atrophy in Alzheimer’s disease?
The pathological substrate of the cortical atrophy seen in this study also requires further elucidation. Early cortical atrophy in Alzheimer’s disease is associated primarily with loss of synapses and the extent and complexity of dendritic arborisation 20,21.
What is posterior cortical atrophy of the brain?
This difficulty is secondary to atrophy of the back (posterior) part of the brain. This is the region responsible for visual processing and spatial reasoning. Posterior cortical atrophy is most commonly due to Alzheimer’s disease (over 80%) but may be due to other neurological conditions, such as Lewy body dementia or corticobasal degeneration.
