Acute Dizziness with Hearing Loss Autoimmune Inner Ear Disease
... • ± Hearing loss • Visual disturbances • rapid flexion-extension of head results in cervical muscles spasm, impairing blood flow through the vertebro-basilar circulation Tests: Positional nystagmus w/ head hyperextended; COR gains increased (likely secondary to reduced neck movements.) ENG findings: ...

The Ocular Side-Effects of Vigabatrin
... Treatment dose and duration Several studies have not identified a relationship between the daily or cumulative dose of vigabatrin and the risk of VAVFC. It has therefore been postulated that the drug response is idiosyncratic in nature. By contrast other studies, with more precise data on dose and d ...

Evaluating the Patient With Suspected Radiculopathy

Intraspinal lesions can cause weakness due to their effects on the motor axons which originate in the anterior and lateral gray matter and pass through the lumbar spine as spinal roots.

Phantosmia
Phantosmia is an olfactory hallucination. A hallucination is the sensory perception of something with no basis in reality, as opposed to an olfactory illusion, which is a misinterpretation of a physical stimulus; in the case of an odor it is known as parosmia. Phantosmia is the perception of a smell in the complete absence of any physical odor. The perceived odor can range from pleasant to disgusting. Although the causes of phantosmia are uncertain, it often occurs with neurological and psychological disorders such as schizophrenia, mood disorders, Parkinsons disease, epilepsy, neuroblastoma, and frequent migraines.Galen also mentioned olfactory hallucinations in his work and stated that these hallucinations constitute the signs of an oncoming disease.Different types of phantosmia include: Unirhinal (single nostril), episodic, and recurrent, where the activation of brain's GABAergic system seems to play a role in the inhibition of the unirhinal phantosmia.Treatments for phantosmia range from drug therapies (e.g., venlafaxine) and brain stimulation therapies to invasive surgical procedures involving removal of the olfactory bulbs or olfactory epithelium.The word phantosmia is a noun of Greek origin. It is composed of two words: (1) phant- meaning ""phantom"" and (2) -osmia (from osme) meaning ""smell"".
