ReviewChronic traumatic encephalopathy - neuropathology in athletes and war veterans.
The neuropathologic findings of chronic traumatic encephalopathy (CTE) were first described almost 40 years after the first clinical reports. We reviewed the literature and describe the neuropathological findings seen primarily in professional athletes and more recently, in war veterans. ⋯ The potential prevalence of CTE, as well as the vulnerable populations involved, makes research into this topic crucial. Currently, a comprehensive neurological exam, neuropsychiatric assessment, and standard radiographic techniques such as conventional MRI are the mainstay of diagnosis. There is a pressing need for the prevention of CTE and the development of non-invasive diagnostic tests in order to develop therapies that may be of clinical use to athletes and blast injury veterans during their lifetimes.

ReviewContemporary imaging of mild TBI: the journey toward diffusion tensor imaging to assess neuronal damage.
To follow the progression of neuroimaging as a means of non-invasive evaluation of mild traumatic brain injury (mTBI) in order to provide recommendations based on reproducible, defined imaging findings. ⋯ Modern imaging techniques, when applied in the appropriate clinical setting, may serve as a valuable tool for diagnosis and management of patients with mTBI. An understanding of modern neuroanatomical imaging will enhance our ability to analyse injury and recognize the manifestations of mTBI.

The American population above 65 years of age will double by 2050, and more nonagenarians will present to neurosurgeons for treatment for subdural hematomas (SDH), common in the elderly. Healthcare providers, and patients' relatives, often choose treatment when there is little chance of recovery. Hospital mortality is 24% (n = 5) in chronic subdural hematoma (cSDH) patients over 65 years, but there are no studies on cSDH outcomes in patients aged over 90 years. This retrospective study evaluates outcomes in this population. ⋯ Clinical presentation with cSDH is a sentinel event for patients aged 90 years or older; 67% have surgical intervention. Disposition does not vary with surgical or non-surgical treatment. Only 24% of patients of this age group presenting with cSDH return home despite a good admission GCS.
