Basal Ganglia (Overview)

This is the term for several areas of the brain that work together as a functional unit: the striatum (caudate and putamen), the globus pallidus, the substantia nigra, and the subthalamic nucleus. The most well known function of the basal ganglia is voluntary motor control, but it is also involved in development of routine behaviors; eye movements; and cognitive and emotional functions.

Is a small (3mm) hyperintensity in the basal ganglia significant or not. Also what are the causes?

Is a small (3mm) hyperintensity in the basal ganglia significant or not. Also what are the causes?

MRI brain: It is likely not significant however the results of your MRI study should be discussed with a neurologist to put into context what the 3 mm spot means relative to the entire MRI study and your medical problems. The causes of the bright spots on MRI studies (T2) of the brain are many and range from aging, migraines, mini-strokes, bleeding, atherosclerosis, multiple sclerosis, and metastatic tumors. ...Read more

Has anyone studied basal ganglia volume in asperger's syndrome?

Has anyone studied basal ganglia volume in asperger's syndrome?

Yes: There are several studies suggesting increased volume of some parts of the basal ganglia are associated with increased likelihood of engaging in repetitive movements. Nothing that really offers insight into autism itself, however. ...Read more

What could an oval shaped low density lesion in the lower aspect of the right basal ganglia measuring 1cm be?

What could an oval shaped low density lesion in the lower aspect of the right basal ganglia measuring 1cm be?

lesion in the brain: Any lesion in the brain, in this case a 1 cm lesion in the base of the right basal ganglia (near brainstem), is abnormal. There is no guessing about what it could be. I presume this was a ct or an MRI ordered by a primary care physician or neurologist. Whoever has this needs to have neurologic and possibly neurosurgical consultations. ...Read more

Is it possible for cysts in the basal ganglia to cause any outward symptoms? If so, what would these include?

Is it possible for cysts in the basal ganglia to cause any outward symptoms?  If so, what would these include?

Usually asymptomatic: See a neurologist to establish if your symptoms ( undescribed by you) are related to "CYST IN BASAL GANGLION" ...Read more

A 14x6x6mm non-enhancing signal abnormality inferior to the basal ganglia, no high rcbv, te 135ms cho/naa ratio - 1.3: heterotopia? Low grade?

A 14x6x6mm non-enhancing signal abnormality inferior to the basal ganglia, no high rcbv, te 135ms cho/naa ratio - 1.3:  heterotopia? Low grade?

Serial Imaging : Your MRI could be consistent with low grade neoplasm or a benign finding. The best option in these cases where it is unclear is to follow the area closely with repeat MRI at say 3 month intervals. If this is benign it will stay the same. If it grows it is likely a neoplasm. ...Read more

What is basal ganglia calcification?

BG Calcification : The basal ganglia are a part of the brain. It is common for calcifications to develop in these regions as we get older without clinical significance. In children this would be more worrisome. ...Read more

Neuroanatomy-basal ganglia and internal capsule, what are these?

Neuroanatomy-basal ganglia and internal capsule, what are these?

Basal Ganglia: Basal ganglia are group of structures linked to the Thalamus in the base of the brain, involved in coordination of movements. They consist of Caudate nucleus, Putamen & Globus pallidus. Internal capsule is White matter in the inferomedial part of each cerebral hemisphere, which carries information past the Basal Ganglia, carrying information from Cerebral cortex to Brainstem & Spinal cord. ...Read more

How to differentiate cerebellar dysfunctions from basal ganglia dysfuntions?

How to differentiate cerebellar dysfunctions from basal ganglia dysfuntions?

Several ways: BG has resting tremor, Cerebellar has action tremor. Muscle tone up in BG, decreased in cerebellum. Gait ataxia if cerebellar, but short hesitant steps in BG. Just a couple ways that neurologists look at findings. If you think you might have one or the other problems, might consider a visit to a neurologist. ...Read more

Hi doctors, was just wondering what is a lacunar infarcat left basal ganglia?

Hi doctors, was just wondering what is a lacunar infarcat left basal ganglia?

Small Stroke.: Those findings are small strokes of specific areas of the brain that are subcortical or below the cortex. Two of the three mechanisms for those strokes are related to a chronic vascular disease associated with hypertension. Other likely risk factors include diabetes mellitus and possibly smoking. Symptoms will depend on what was affected. See your Neurologist or PCP. Not a 'classic stroke'. ...Read more

How can you differentiate cerebellar dysfunctions from basal ganglia dysfuntions?

How can you differentiate cerebellar dysfunctions from basal ganglia dysfuntions?

Yes: Somewhat easy for a trained neurologist, as different types of tremors, muscle tone, coordination, gait and balance, and our imaging studies, such as MRI and PET scans can separate out the location of the problems. ...Read more

What does it mean to have atrophic changes with  basal ganglia lacunar infracts.?

Brain changes: These finding suggest a chronic process which has caused damage to parts of the brain. The most common culprit is atherosclerotic disease of the arteries. Additional evaluation by a physician is recommended. ...Read more
