Transient Ischemic Attack l: Introduction

Transient Ischemic Attack l: Introduction

A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...

Prosopagnosia

Prosopagnosia

Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

Area of Science:

Neurology
Radiology
Ophthalmology

Background:

A 56-year-old female presented with symptoms following a fall.
Imaging revealed an acute right-sided convexity subdural hematoma.

Observation:

A computed tomography angiogram was performed.
The patient developed bilateral cortical blindness one hour post-procedure.

Findings:

The patient's vision was fully restored.
A diagnosis of transient cortical blindness was established.

Implications:

Transient cortical blindness is a rare complication of intra-arterial iodinated contrast agents.
This case underscores the importance of recognizing this potential adverse event in neuroimaging procedures.
