Non-Invasive Diagnosis Of Traumatic Dementia At An Early Stage – Part 1 of 3
Non-Invasive Diagnosis Of Traumatic Dementia At An Early Stage. A “virtual biopsy” may ease diagnose a degenerative brain disorder that can occur in authority athletes and others who suffer repeated blows to the head, says a new study. Symptoms of chronic traumatic encephalopathy (CTE) can include memory problems, impulsive and erratic behavior, despair and, eventually, dementia. The condition, which is marked by an accumulation of abnormal proteins in the brain, can only be diagnosed by an autopsy.
But a specialized imaging technique called magnetic resonance spectroscopy (MRS) may furnish a noninvasive way to diagnose CTE at an early stage so that treatment can begin before further brain damage occurs, say US researchers. MRS – sometimes referred to as “virtual biopsy” – uses intense magnetic field and radio waves to gather information about chemical compounds in the body. The researchers used MRS to examine five retired gifted male football players, wrestlers and boxers, ages 32 to 55, with suspected CTE and compared them to a control group of five age-matched men.
