ReviewChronic traumatic encephalopathy: where are we and where are we going?
Chronic traumatic encephalopathy (CTE, previously called punch drunk and dementia pugilistica) has a rich history in the medical literature in association with boxing, but has only recently been recognized with other contact sports, such as football and ice hockey, as well as with military blast injuries. CTE is thought to be a neurodegenerative disease associated with repeated concussive and subconcussive blows to the head. There is characteristic gross and microscopic pathology found in the brain, including frontal and temporal atrophy, axonal degeneration, and hyperphosphorylated tau and TAR DNA-binding protein 43 pathology. ⋯ Here we review the CTE literature to date. We also draw on the literature from mild traumatic brain injury and other neurodegenerative dementias, particularly when these studies provide guidance for future CTE research. We conclude by suggesting seven essential areas for future CTE research.

ReviewMisdiagnosis of multiple sclerosis: frequency, causes, effects, and prevention.
A diagnosis of multiple sclerosis is heavily influenced by clinical judgment. Misdiagnosis of multiple sclerosis is common and has important consequences for patients and the cost of healthcare. Although rigorous data about the frequency and causes of misdiagnosis are lacking, misinterpretation and misapplication of clinical and radiographic diagnostic criteria and terminology are likely important factors. Appropriate and stringent application of diagnostic criteria and continued vigilance for "red flags" suggesting alternative diagnoses are strategies critical for prevention of misdiagnosis.
