What research is out on aphasia?

Aphasia: There is an enormous literature out there on aphasia which was originally described in the 1860s. The origin of aphasia and the brain location where it occurs is now well described. It most commonly occurs as a result of trauma or a stroke or a bleed in the brain. Research in treating these issues still has a long way to go in achieving any sort of brain regeneration.

The disorders which make up the Primary Progressive Aphasias are driving a lot of research in recent years. These are specific neurodegenerative disorders with involvement in the frontal and temporal lobe of the brain, location involved correlating with certain types of PPA. tDCS has low cost, high safety, and is non invasive may augment usual behavioral intervention and reduce decline in PPA
