Symptom 9: Sleep Disorders – Unrest in Rest
Sleep disorders, including insomnia and sleep apnea, frequently surface in individuals with spinocerebellar ataxia. The link between SCA and sleep disturbances is not entirely understood, but it’s believed that the degeneration of the cerebellum and other associated neurological changes could disrupt the sleep cycle.
The onset of sleep disorders can be gradual. Initially, individuals might find it slightly more challenging to fall asleep or might wake up frequently during the night. Some might feel less refreshed upon waking up, regardless of the number of hours spent sleeping. These minor disturbances might be easily overlooked or attributed to stress or other lifestyle factors.
However, as SCA progresses, the sleep disturbances can become more severe. Individuals might struggle with chronic insomnia, making it difficult for them to fall asleep or maintain sleep. Others might develop sleep apnea, a condition characterized by pauses in breathing during sleep. This can lead to daytime sleepiness, fatigue, and cognitive difficulties.
Addressing sleep disorders is crucial as poor sleep quality can exacerbate other SCA symptoms, contribute to physical and mental health problems, and significantly lower quality of life. Sleep hygiene practices, cognitive behavioural therapy for insomnia (CBT-I), and in some cases, specific medications can help manage sleep disorders. However, persistent sleep problems warrant a discussion with a healthcare provider, who can recommend appropriate diagnostic tests and treatments. (9)
