Dejerine–Roussy syndrome or thalamic pain syndrome is a condition developed after a thalamic stroke, a stroke causing damage to the thalamus. [1] Ischemic strokes and hemorrhagic strokes can cause lesioning in the thalamus.
Pure sensory stroke: contralateral thalamus , internal capsule, corona radiata, midbrain Marked by numbness (loss of sensation) on one side of the body; can later develop tingling, pain, burning, or another unpleasant sensation on one side of the body. Mixed sensorimotor stroke: thalamus and adjacent posterior internal capsule, lateral pons
Occlusions of the branches of the PCA that supply the thalamus can result in central post-stroke pain and lesions to the subthalamic branches can produce “a wide variety of deficits”. [1] Left posterior cerebral artery syndrome presents alexia without agraphia; the lesion is in the splenium of the corpus callosum.
An MRI was done the next morning and Dr. Volpi concluded that she had a left thalamic stroke. The stroke damaged her left thalamus which in turn affects the right. Christine Lee had a hole/flap called patent foramen ovale (PFO) in her heart which was an undiagnosed birth defect. This created a blood clot that went through her body and made its ...
One study found that up to 8% of people who have had a stroke will develop central post-stroke pain, and that the pain will be moderate to severe in 5% of those affected. [78] The condition was formerly called "thalamic pain", because of the high incidence among those with damage to the thalamus or thalamic nuclei. Now known as CPSP, it is ...
Vascular thalamic amnesia occurs when the thalamus is affected by Korsakoff's syndrome or damaged by lacunar infarcts or hemorrhages. [1] Another common cause for damage to the thalamus that may contribute to the development of amnesia is a stroke. [ 2 ]
A thalamus damaged by a stroke can lead to thalamic pain syndrome, [67] which involves a one-sided burning or aching sensation often accompanied by mood swings. Bilateral ischemia of the area supplied by the paramedian artery can cause serious problems including akinetic mutism , and be accompanied by oculomotor problems.
In 1858 doctor Thomas Inman described four of thirty discovered cases with cerebral softening. Each case was similar to the previous article. There was some atheroma in the internal brain arteries that led to the cerebral softening of the left side of the brain around the left lateral ventricle, thalamus and corpus striatum. There were similar ...
