ReviewObstructive sleep apnea and its controversial effects on cognition.
Obstructive sleep apnea syndrome is a sleep disorder that may affect many brain functions. We are interested in the cognitive consequences of the condition with regard to the quality of life of individuals with this disorder. ⋯ We report findings and opinions on structural and cognitive brain changes in individuals affected by obstructive sleep apnea by highlighting the involvement of executive functions and the possible reversibility of signs following-treatment with continuous positive airway pressure. Much research has been done on this issue but, to the best of our knowledge, a review of the present state of the literature evaluating different points of view has not yet been carried out.

The role of neuroimaging in the diagnosis and management of mild traumatic brain injury (TBI) is evolving. In general, the structural imaging techniques play a role in acute diagnosis and management, while the functional imaging techniques show promise for clarification of pathophysiology, symptom genesis, and mechanisms of recovery. ⋯ It is, therefore, important to be aware of the advantages and limitations of the various available imaging modalities. This paper selectively reviews the pertinent literature on the structural and functional imaging in mild TBI.

ReviewDetermining random responding for the category, speech-sounds perception, and Seashore Rhythm tests.
A formula is presented for determining if scores from the Category, Speech-Sounds Perception, and Seashore Rhythm tests are significantly different from random responding. Confidence intervals for random responding are also presented. Results of published studies involving normative and non-normal subjects are reviewed, and the percentage of subjects responding in the random range are presented. Normative subjects' scores on the Category and Speech-Sounds Perception tests do not fall into the random range, but high percentages of their Seashore Rhythm Test scores do fall into the random range.
