Purpose
The purpose of this study is to evaluate whether damage to the hypothalamus due to craniopharyngioma or consequent surgery may involve the sleep-wake regulatory system, resulting in sleep disturbances and sleepiness.
Methods
Seven craniopharyngioma patients and 10 healthy controls were evaluated with sleep questionnaires including the Epworth Sleepiness Scale, polysomnography, and a multiple sleep latency test (MSLT). Five patients and eight controls had lumbar puncture performed to determine hypocretin-1 levels.
Results
Patients tended to feel sleepier than control individuals of the same age (p = 0.09). No subjects had symptoms of hypnagogic hallucinations, sleep paralyses, or cataplexies. Four patients and one control had periodic leg movements (PLMs). One patient had fragmented sleep pattern, rapid eye movement (REM) sleep without atonia, and PLMs. One patient had short sleep periods during the daytime. Four patients had fragmented sleep pattern. With the MSLT, four patients and two controls had mean sleep latency of < 8 min. One patient and three controls had sudden onset of REM sleep in 2/5 and 3/5 sleep periods, respectively. All subjects showed normal hypocretin-1 levels. Four patients had electrophysiological findings indicative of central hypersomnia including one patient meeting the criteria of narcolepsy.
Conclusion
The sleep-wake regulatory system may be involved in craniopharyngioma patients.
