What does a thalamic stroke affect?

Thalamic strokes fall under the category of subcortical strokes or lacunar strokes, which affect the deeper brain regions beneath the cerebral cortex, as opposed to the outer cortical region. When a stroke occurs, it is a medical emergency as brain cells begin to die within minutes of losing blood supply.

What part of the body does the thalamus control?

Your thalamus is an egg-shaped structure in the middle of your brain. It’s known as a relay station of all incoming motor (movement) and sensory information — hearing, taste, sight and touch (but not smell) — from your body to your brain.

What is left thalamic infarct?

Thalamic infarcts refer to ischemic strokes which affect the subcortical grey matter complex of nuclei known as the thalamus.

What artery supplies thalamus?

The primary blood supply of the thalamus is from the posterior cerebral artery.

How do you code a thalamic stroke?

Ischemic strokes and Hemorrhagic strokes can cause lesioning in the thalamus. So if you have Dx as a Thalamic Stroke then as per Index of diseases of ICD 9 CM, 434.91 is the only option.

What is a thalamus stroke?

What is a thalamic stroke? Strokes are caused by a disruption of blood flow to your brain. Without blood and nutrients, your brain tissue quickly begins to die, which can have lasting effects. A thalamic stroke is a type of lacunar stroke, which refers to a stroke in a deep part of your brain.

Where is the thalamic region?

The thalamus is a paired gray matter structure of the diencephalon located near the center of the brain. It is above the midbrain or mesencephalon, allowing for nerve fiber connections to the cerebral cortex in all directions — each thalamus connects to the other via the interthalamic adhesion.

Is thalamic aphasia fluent?

In sum, thalamic aphasia can be described as mild, with fluent spontaneous speech and impairments within higher-order language skills such as complex-understanding of speech and verbal fluency as well as unimpaired comprehension and repetition.

What does right thalamus control?

While the thalamus is classically known for its roles as a sensory relay in visual, auditory, somatosensory, and gustatory systems, it also has significant roles in motor activity, emotion, memory, arousal, and other sensorimotor association functions.

What is a bilateral thalamic stroke?

Bilateral thalamic infarcts are unusual presentations of posterior circulation stroke; once they are diagnosed by an adequate neuroimaging protocol, a further evaluation to define the cause is necessary. Cardioembolism should always be considered in relatively young patients.

What happens at the thalamus?

The thalamus relays sensory impulses from receptors in various parts of the body to the cerebral cortex. A sensory impulse travels from the body surface towards the thalamus, which receives it as a sensation. This sensation is then passed onto the cerebral cortex for interpretation as touch, pain or temperature.

What is Nonfluent aphasia?

Aphasia is broken down into two categories: Nonfluent aphasia. Speech is difficult or halting, and some words may be absent. However, a listener can still understand what the speaker is trying to say.

What is a stroke in the thalamus?

Understanding a Stroke in the Thalamus A stroke occurs when the supply of blood to the brain is compromised. This can happen when an artery leading to or within the brain becomes clogged by a blood clot (known as an ischemic stroke) or when a blood vessel bursts (known as a hemorrhagic stroke).

What are the secondary effects of a thalamic stroke?

Speech and Cognitive Therapy Some potential secondary effects of a thalamic stroke include speech difficulties and changes in executive function such as working memory loss or changes in attention span. A Speech-Language Pathologist is the best expert to seek help from.

How is a thalamic stroke diagnosed?

A thalamic stroke can be diagnosed with imaging studies such as: CT scan. CT scan is a test that combines X-rays and computer scans. The result is a detailed picture that can show problems with your blood vessels and organs. MRI. This is a test that lets your doctor see detailed pictures of the inside of your body.

Which region of the thalamus is involved in tuberothalamic territory infarction?

In some patients with tuberothalamic territory infarction, the stroke is confined to the most anterior region of thalamus.
