100 Possible Causes for Abnormal Sleep-Wake Cycles

  • Angelman Syndrome

    Sleep disorders are also common, often characterized by abnormal sleep-wake cycles.[ncbi.nlm.nih.gov] The consensus guidelines for Angelman syndrome (AS) consider abnormal sleep-wake cycles and diminished need for sleep as associated features.[ncbi.nlm.nih.gov] Patients may also exhibit wide mouths with unusual tongue/mouthing behaviors, hypopigmentation, and abnormal sleep-wake cycles. Older patients may experience obesity.[dnatesting.uchicago.edu]

  • Insomnia

    The cause is unknown, but it seems to affect primarily the thalamus with disruptions in the sleep-wake cycle.[medical-dictionary.thefreedictionary.com] Onset is typically in midlife, characterized by progressive insomnia, hallucinations, and motor abnormalities followed by stupor and coma ending in death within 6 months to[medical-dictionary.thefreedictionary.com]

  • Delirium

  • Alzheimer Disease

    […] of the sleep-wake cycle.[ajp.psychiatryonline.org] Therefore, we analyzed the data for differences between the patients who were rated as “usually has a regular sleep-wake cycle” and the patients who had some abnormalities[ajp.psychiatryonline.org] Only two patients had sleep-wake disturbances more than “sometimes has an irregular sleep-wake cycle.”[ajp.psychiatryonline.org]

  • Alcohol Withdrawal

    Reversal of the sleep-wake cycle is common.[emedicine.medscape.com] Neurological symptoms may include the following: Dysphasia Dysarthria Tremor Asterixis in hepatic encephalopathy and uremia Motor abnormalities Patients with delirium who[emedicine.medscape.com]

  • Temporal Lobe Epilepsy

    The nature of the seizures depends on many factors, such as the person’s age, the sleep-wake cycle, prior injuries to the brain, genetic tendencies, medications, which circuits[web.archive.org] During normal cycles of waking and sleeping, the brain cells create varying electrical activity.[wikihow.com] This means that during a seizure, large numbers of brain cells are activated abnormally at the same time. It is like an "electrical storm" in the brain.[web.archive.org]

  • Tonic-Clonic Seizure

    The nature of the seizures depends on many factors, such as the person’s age, the sleep-wake cycle, prior injuries to the brain, genetic tendencies, medications, which circuits[epilepsy.com] This means that during a seizure, large numbers of brain cells are activated abnormally at the same time. It is like an "electrical storm" in the brain.[epilepsy.com]

  • Brain Stem Infarction

    Sleep-wake cycles are absent in patients with coma.[emedicine.medscape.com] Coma generally is associated with oculomotor abnormalities, and motor abnormalities may be present.[emedicine.medscape.com]

  • Hypoxia

    […] seizures, and (4) absence of sleep-wake cycle at 48 hours.[emedicine.medscape.com] Caution in interpreting early severe background abnormalities needs to be applied because reverting to normal background pattern in few days of life can be associated with[emedicine.medscape.com] EEG characteristics associated with abnormal outcomes include (1) background amplitude of less than 30 mV, (2) interburst interval of more than 30 seconds, (3) electrographic[emedicine.medscape.com]

  • Isolated optic nerve hypoplasia

    Disturbance of circadian sleep rhythm, resulting in abnormal sleep-wake cycles, is noted in one-third of children with ONH.[ipfs.io] Disturbance of circadian sleep rhythm , resulting in abnormal sleep-wake cycles, is noted in one-third of children with ONH.[en.wikipedia.org]
