Insights

Disulfiram intoxication can cause oculogyric crisis, a condition affecting eye movements. Brain imaging revealed basal ganglia and substantia nigra lesions, suggesting a link between these brain areas and the crisis.

Area of Science:

  • Neuroscience
  • Neurology
  • Toxicology

Background:

  • Disulfiram is used to treat alcohol dependence.
  • Oculogyric crisis is a rare extrapyramidal side effect characterized by tonic deviation of the eyes.

Purpose of the Study:

  • To report a case of oculogyric crisis following disulfiram intoxication.
  • To investigate the neuroanatomical basis of this adverse reaction.

Main Methods:

  • Case report of a patient with oculogyric crisis after disulfiram exposure.
  • Brain Magnetic Resonance Imaging (MRI) to identify structural lesions.

Main Results:

  • The patient developed oculogyric crisis one month after disulfiram intoxication.
  • Brain MRI revealed lesions in the bilateral globus pallidus and left substantia nigra.
  • These affected areas are critical components of the basal ganglia circuitry.

Conclusions:

  • Disulfiram intoxication can lead to oculogyric crisis.
  • Pathological reorganization of basal ganglia circuits, affecting the globus pallidus and substantia nigra, may underlie the observed ocular motor dysfunction.

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Olfactory Receptors: Location and Structure

The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

CNS Depressants: Alcohol and Nicotine

Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

Glaucoma: Overview01:25

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Parkinson's Disease: Treatment

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...
