Neurological sleep disorders
Sleep problems are common but not all have neurological causes. Neurological sleep disorders include sleep-related epilepsy (nocturnal seizures manifesting as parasomnias, rhythmic movements or arousal disorders), restless legs syndrome (RLS) and periodic limb movement disorder (PLMD), narcolepsy (excessive daytime sleepiness with or without cataplexy), REM sleep behaviour disorder (dream enactment behaviour, often a prodrome to synucleinopathies such as Parkinson's disease and Lewy body dementia), and sleep-related breathing disorders with neurological comorbidity.
Restless legs syndrome produces an irresistible urge to move the legs, typically worse at rest and in the evening, with temporary relief by movement. It is associated with iron deficiency, renal failure and pregnancy. REM sleep behaviour disorder involves loss of normal REM atonia with dream-enacting behaviour; it is strongly associated with future neurodegenerative disease. Accurate identification of the specific sleep disorder guides targeted treatment rather than generic sleep hygiene advice.

Evaluation approach
Evaluation begins with detailed sleep history — onset, duration, pattern (insomnia, hypersomnia, parasomnia, breathing disturbance), triggers, associated symptoms, and impact on daytime function. Sleep diary (1–2 weeks) captures sleep-wake pattern, timing and consistency. Screening questionnaires (Epworth Sleepiness Scale, STOP-BANG for sleep apnoea, International RLS Scale) quantify symptom severity.
Neurological examination screens for signs of underlying conditions (parkinsonism, cognitive impairment, neuropathy). Blood tests may include ferritin (for RLS), thyroid function and vitamin B12. Polysomnography (sleep study) is arranged when sleep apnoea, parasomnias, narcolepsy or sleep-related seizures are suspected. Multiple sleep latency testing (MSLT) confirms narcolepsy when indicated. EEG may be considered when nocturnal events are suspicious for seizures. Dr. Jitendra Prasad Yadav (NMC 8029) provides structured evaluation at Kathmandu Neurology Clinic & Cognitive Center, Durbar Marg, Opposite of Yak & Yeti Hotel.
When to see a neurologist for sleep problems
A neurologist should evaluate sleep problems when symptoms suggest a neurological cause: excessive daytime sleepiness despite adequate sleep duration, dream-enacting behaviour (hitting a bed partner, falling out of bed), nocturnal seizures or unusual movements during sleep, severe restless legs despite basic measures, or sleep problems occurring alongside headache, cognitive decline or movement disorder.
Sleep problems also worsen neurological conditions — poor sleep increases migraine frequency, lowers seizure threshold and accelerates cognitive decline. Addressing sleep in the context of neurological disease requires specialist assessment. Dr. Jitendra evaluates both the sleep disorder and its neurological context at Kathmandu Neurology Clinic, Durbar Marg, Opposite of Yak & Yeti Hotel, ensuring treatment addresses the complete picture rather than isolated symptoms.
- Excessive daytime sleepiness despite adequate sleep — evaluate narcolepsy, sleep apnoea
- Dream-enacting behaviour — evaluate REM sleep behaviour disorder
- Restless legs at night — check ferritin, evaluate for RLS
- Nocturnal seizures or unusual movements — consider video-EEG monitoring
- Sleep problems with headache, cognitive decline or movement disorder — neurological context
