In many cases, it is the result of sleep deprivation, circadian rhythm disruption or the type of the procedures. The effective way to restore fatigue-induced functionality is a short-term daytime sleep. The term «power nap» has been introduced to emphasize its positive effect on some cognitive functions. This review considers the effects of short-term daytime sleep of various duration on memory consolidation. Short-term daytime sleep for up to 30 minutes between 1 p.m and 3 p.m can be recommended to improve the effectiveness of the intellectual work. These measures are intended to improve declarative memory without subsequent sleep inertia.In real clinical practice, back pain in young patients is associated with neurological manifestations of degenerative changes in the lumbosacral spine.

In neurological practice, sacroiliitis is similar to myofascial syndromes and can disguise as degenerative diseases of the spine, so early diagnosis and proper therapy are of particular importance. Awareness of doctors about the features of examination of young patients, the use of neuroimaging techniques (CT, MRI), laboratory diagnostics, will help to improve the results of therapy. Prescription of NSAIDs with a pronounced anti-inflammatory potential will slow down the progression of the inflammatory process.Treatment re
