Outcome and Prognosis of Microsurgical Decompression in Idiopathic Severe Common Fibular Nerve Entrapment: Prospective Clinical Study.

Objective: Compression of the common fibular nerve at the level of the fibular neck is considered to be the most frequent lower limb entrapment syndrome, which can be either idiopathic or secondary. Decompressive surgery is indicated only after failure of conservative treatment and/or severe neurologic deficit. The effectiveness of microsurgical decompression has been established only for secondary entrapment syndrome.

Sleep and Alzheimer's disease.

Sleep disorders are frequent in Alzheimer's disease (AD), with a significant impact on patients and caregivers and a major risk factor for early institutionalization. Micro-architectural sleep alterations, nocturnal sleep fragmentation, decrease in nocturnal sleep duration, diurnal napping and even inversion of the sleep-wake cycle are the main disorders observed in patients with AD. Experimental and epidemiological evidence for a close reciprocal interaction between cognitive decline and sleep alterations is growing.
