DizzinessSleep Disorders

Dizziness could be a result of sleepiness in its extreme form. It can be observed in people with sleep deprivation and, especially as a side effect, when sleep medication is administered.

How to define Diziness?

Dizziness refers to an impairment in spatial perception and stability, as defined by Dorland’s Medical Dictionary. It is considered imprecise, by Medical Sybject Heading (MeSH). It can be used to mean vertigo, presyncope, disequilibrium,  as described by Disorders of the Nervous system – Reeves & Swenson.  Dizziness commonly manifests as a non-specific feeling, such as: giddiness or foolishness, as described by UptoDate online.

Several terms, which might be associated with sleepiness and related dizziness:

  • Vertigo is a specific medical term used to describe the sensation of spinning or having one’s surroundings spin about them. Disequilibrium is the sensation of being off balance, and is most often characterized by frequent falls in a specific direction. Presyncope is light-headedness, which is muscular weakness and feeling faint. The opposite to presynco is a syncope, which is actually fainting.
  • Non-specific dizziness is often psychiatric in origin. It is a diagnosis of exclusion and can sometimes be brought about by hyperventilation, whereabout an access of oxigen in the blood stream causes symptoms of dizziness.
