Mild traumatic brain injury is arguably one of the most highly publicized neurologic disorders. Immediate signs and symptoms of concussion include vacant stare, delayed verbal and motor responses, confusion and inability to focus attention, disorientation, slurred or incoherent speech, gross observable decrease in coordination, emotions out of proportion to circumstances, memory deficits, or any period of loss of consciousness. Most concussions resolve spontaneously within 10 to 14 days.

Indications for rivastigmine include the symptomatic treatment of mild to moderately severe Alzheimer dementia and mild to moderate dementia related to Parkinson disease. Ongoing studies are examining the effect of rivastigmine in patients with severe Alzheimer disease. Rivastigmine is contraindicated in patients with known hypersensitivity to rivastigmine, other carbamate derivatives, or to any excipients used in the formulation. Another contraindication is severe liver impairment.

Headache & Pain
Primary cough headache is typically bilateral, has a sudden onset, and, after peaking, almost immediately dissipates over seconds to a few minutes, with the ICHD-3 permitting residual pain for up to 2 hours. It is precipitated rather than aggravated by coughing. The International Headache Society criteria specify that structural lesions must be ruled out by neuroimaging before the diagnosis of primary cough headache can be made.
