Clinical neurological examination, neuropsychology, electroencephalography and computed tomographic head scanning in...

Twenty active amateur boxers were studied seeking evidence of neurological dysfunction and, if present, the best method for detecting it. Seven of these boxers had an abnormal clinical neurological examination, eight an abnormal EEG and nine of 15 examined had abnormal neuropsychometry. The CT scan was abnormal in only one. An abnormal clinical examination correlated significantly (p less than 0.05) with an increasing number of fights, and an abnormal EEG with decreasing age (p less than 0.05). In several of the neuropsychometric tests, the boxers were significantly worse than controls (p less than 0.05). Neuropsychometry was the best method for detecting neurological dysfunction.
