Hello,

Gliosis is a proliferation of astrocytes in the brain, in areas of damage. This is seen in areas of the brain in neurodegenerative diseases like Alzheimer's, Parkinson's, multiple sclerosis, prion's disease and others. These can vary in size deending on the extent of damage.

Do get back with any other queries

After a traumatic asphyxiation, small, stone-like, brownish fragments started coming away from inside my head through my nose with what may have been dry blood?
What would this have been, please?
I had bed rest for 3 days with my feet elevated.

Thankyou

eamination states "indicate foci of gliosis or demyelination."  Also "multiple foci of raised T2 and FLAIR signal in both cerebral hemispheres.  What does this mean, and what illness would this indicate.

Hi,

As I have already said, any area of brain tissue destruction can lead to gliosis. The causes that I have stated above are the most well defined causes of foci of gliosis. Other nonspecific causes like migraine, small vessel disease and demyelination are possibilities. The final diagnosis depends on the combination of examination, history and investigations. Investigation alone cannot be used to diagnose a disease
