What are functions of the thalamus?

What are functions of the thalamus?

Sensory relay : The thalamus is a complex brain structure, but in simplest views it is mainly a sensory relay station, receiving input from the outside world through the spinal cord and sending processed information up to the cortex for interpretation. It is therefore important to sensory integration. The input it provides the cortex can modify motor activity and other functions. ...Read more

Is infarcture in the thalamus treatable?

MRI finding?: You describe a lesion in the deep brain. The cause must be determined. It could be a minor finding of minor significance. It could be the sign of a serious neurological condition. It may be an incidental finding on MRI of no clinical significance. Your doctor should discuss the significance of this finding with you in detail. ...Read more

Old stroke: Chronic implies longer than 3-6 months. Brain infarct is a stroke, due to blood vessel obstruction. Risk factors might include hypertension, diabetes, high cholesterol, and the presence of an old stroke predicts future stroke risk. So, likely best to start an anti-platelet drug.

Can the thalamus be associated with any kind of seizures?

Can the thalamus be associated with any kind of seizures?

Critical importance: It is clear that the thalamus plays a substantial role in seizure generalization and brain region interconnections, but is not usually the source of seizure origination, even in those folks who have had prior strokes. In yrs past, the thought of cerebellar electrical stimulation to affect thalamic function, was considered to control seizure activity. ...Read more

Surgical incision into the thalamus, what are the risks of doing this?

Surgical incision into the thalamus, what are the risks of doing this?

Speak w neurosurgeon: There are very few indications for operative resection of thalamic lesions, since they are uncommon. Most of the experience have been in children with thalamic tumors. Each case must be individualized, there are several approaches to these lesions. The complications (morbidity) is significant and include visual field defects and hydrocephalus. Then the underlying cancer causes mortality. ...Read more

Hi doctors, can you tell me what is lacunar infarct on right thalamus?

Hi doctors, can you tell me what is lacunar infarct on right thalamus?

Small stroke: A lacunar infarct refers to a small stroke (size wise). However because of their location in the brain, where lots of nerves are crossing over (think major highway interchange in your city), they can sometimes cause major problems. The thalamus is a deep brain structure that is responsible for sorting lots of signals in the brain. ...Read more

Brain MRI showed dark splotches on the thalamus (down-front) and cerebellum (middle), there was nothing there on a scan a month before, what are they?

Difficult to say: without more details. Are you looking at two different types of MRI sequences? Certain structures may normally look brighter on one type of sequence and darker on another. ...Read more

Should improve: Age a big advantage and in spite of small strokes, which can be seen in multiple brain infections, should see steady and gradual improvements over next 12-18 months. The brain does have capacity to cope, recover, and establish alternative pathways. ...Read more

Chronic lacunar infarcts in right thalamus & left basal ganglia after TB meningitis. She's 22 and now on TB meds. Can she become independent again?

Lacunar infarcts: If they really are lacunar infarcts, chances are if she is fully treated and recovered, she will improve enough with physical therapy to be strong enough to take care of herself. You just have to have faith and help her along. She needs all the help and you can provide it. ...Read more
