Basal Ganglia Is An Important Structure In Maintaining Nicotine Dependence
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
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 ...Read more
Small infarcts: Lacunar infarcts occur as a result of localized decreased blood flow resulting in localized cell death. This occurs in the more central penetrating vessels of the brain affecting the brains deep structures such as the putamen (part of the basal ganglia), thalamus, caudate pons and internal capsule. ...Read more
Kernicterus causes spasticity? Why is it sis basal ganglia considered in pyramidal tract? Why not causing rigidity instead like parkinsons?
Spasticity: Basal ganglia and substantia nigra are different structures. Injuring the basal ganglia, such as by stroke, may cause spasticity. Injuring the substantia nigra may cause parkinsons symptoms, such as tremor and rigidity. Rigidity and spasticity are not the same, as you recognize. These two different structures of the brain modulate movement differently, that is why the symptoms are different. ...Read more
Result for my brain MRI -asymmetric decreased attenuation in the left basal ganglia, variant dilated perivascular spaces or punctate chronic lacune. ?
MRI report: This is language used in radiology to describe what they see. Ordinarily, they cannot distinguish a small stroke (lacune) from a perivascular space. A "puntate lacune" though is very small. It is probably just the side view of a blood vessel (aka perivascular). Do you smoke? Do you have high blood pressure? Do you have diabetes mellitus? Atrial fibrillation? These are stroke risk factors. ...Read moreSee 1 more doctor answer
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
