What to Know About Thalamic Strokes
Left MCA stroke. An MCA stroke describes the sudden onset of focal neurologic deficit. This results from brain infarction or ischemia in the territory supplied by the MCA. A brain infarction refers to damage to tissues in the brain due to a loss of oxygen to the area.

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 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.
In addition to having a stroke in the thalamus, you could also suffer from a thalamic infarct. An infarct is when the stroke cuts off oxygen to your tissue to the degree that the tissue dies. Depending on the severity and location within the thalamus, infarcts can present long-lasting and serious consequences.
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.
Sometimes it can take months or even years after a thalamic stroke for pain to develop. It is a relatively common complication, affecting up to 8% of individuals following a stroke.
The thalamus is located deep within the brain in the cerebral cortex, adjacent to the hypothalamus. It is a symmetrical structure, situated on top of the brain stem and on either side of the third cortex.
Your thalamus is your body's information relay station. All information from your body's senses (except smell) must be processed through your thalamus before being sent to your brain's cerebral cortex for interpretation. Your thalamus also plays a role in sleep, wakefulness, consciousness, learning and memory.
Thalamic hemorrhagic strokes are hemorrhagic strokes centered on the thalamus, and often the result of chronic hypertension.
There are three clinical syndromes associated with lateral thalamic infarction: (1) hemisensory loss, hemiataxia, and involuntary movements; (2) pure sensory stroke; and (3) sensory-motor stroke.
What causes thalamic stroke? Like other types of stroke, thalamic stroke can be caused by a blood clot blocking blood flow to the thalamus (ischemic). Or it can be caused by bleeding from a blood vessel in the thalamus (hemorrhagic).
It usually is caused by a blood clot or bleed within the brain. A thalamic stroke is a specific type of stroke that blocks blood flow to the region of the brain known as the thalamus.

stroke occurs when there is disruption of blood flow to brain tissue, this leads to ischemia (deprivation of oxygen) and potentially infarction (dysfunctional scar tissue). Strokes can be either hemorrhagic, or embolic/thrombotic. Hemorrhagic strokes occur as a result of a ruptured cerebral blood vessel. Embolic/thrombic strokes occur as a result of an obstructed cerebral vessel.
What Is Left Thalamic Stroke? Between the cerebral cortex and the mid-brain is a double-lobed mass called the thalamus.
A small stroke in this region sometimes causes sensation loss on the opposite side of the body. However, if a larger stroke occurs that involves the thalamus and adjoining parts of the brain, some paralysis or weakening sometimes results. Recovery from these effects usually occurs over time.
Warning signs of a stroke include unexplained numbness, especially on one side of the body; problems understanding people when they talk; problems responding or speaking; becoming dizzy or having problems maintaining balance; and a sudden, severe headache.
