Prosecutors in Texas and around the country are required to turn what is known as exculpatory evidence over to criminal defendants and the attorneys representing them. Exculpatory evidence is evidence that would exonerate defendants or help to establish their innocence. The U.S. Supreme Court ruled in the 1963 case Brady v. Maryland that prosecutors must turn over material that is pertinent to guilt or innocence before a trial begins, but Texas law goes even further.
Individuals in Texas and elsewhere who experience mental decline may be generally diagnosed with dementia. In many cases, individuals have Alzheimer's disease, but this is not always true. In fact, research has discovered that thousands of people diagnosed with the condition don't actually have it. Instead, they could have a condition called limbic-predominant age-related TDP-43 encephalopathy (LATE). It is caused by deposits of TDP-43 in the brain as opposed to the buildup of plaques.
