What is Putaminal hemorrhage?
The putamen is a common site of hypertensive cerebral hemorrhage. Such hemorrhages show a large range of possible presentations – from enormous hemorrhages involving the white matter of the hemispheres and the ventricular system, to cases occurring without causing any symptoms or neurological signs.
What does the putamen do in the brain?
The putamen is involved in learning and motor control, including speech articulation, language functions, reward, cognitive functioning, and addiction.
What happens when the caudate nucleus is damaged?
Early involvement of the caudate nucleus was found to result in worse outcomes over 4 years of follow-up, including cognitive impairment, depression, and movement problems. Lesions in the caudate nucleus can also result in abulia, also known as apathy or lack of will.
What could lesions of the basal nuclei cause?
Damage to the basal ganglia cells may cause problems controlling speech, movement, and posture. This combination of symptoms is called parkinsonism. A person with basal ganglia dysfunction may have difficulty starting, stopping, or sustaining movement.
What is a putamen infarct?
Stroke damage in a brain region known as the putamen is strongly linked to motor neglect, a condition that makes patients slow to move toward the left side, according to researchers at Washington University School of Medicine in St.
Is putamen part of basal ganglia?
The putamen is a subcortical structure that is part of a group of structures known as the basal ganglia. It is also a component of the dorsal striatum, which includes the putamen and the caudate nucleus.
Is putamen part of the basal ganglia?
The basal ganglia are a cluster of subcortical nuclei deep to cerebral hemispheres. The largest component of the basal ganglia is the corpus striatum which contains the caudate and lenticular nuclei (the putamen, globus pallidus externus, and internus), the subthalamic nucleus (STN), and the substantia nigra (SN).
What disease affects caudate nucleus?
Huntington’s Disease (HD) is a devastating neurodegenerative disease caused by an expanded trinucleotide CAG repeat in the HTT gene. The striatum, comprising the caudate nucleus (CAU) and putamen, is the primary affected brain region in HD where as many as 90% of neurons are lost in late stage disease.
Is the caudate nucleus part of the basal ganglia?
The basal ganglia are a group of structures found deep within the cerebral hemispheres. The structures generally included in the basal ganglia are the caudate nucleus, putamen, and globus pallidus in the cerebrum, the substantia nigra in the midbrain, and the subthalamic nucleus in the diencephalon.
What symptoms would you expect to see in a patient with damage to the basal nuclei quizlet?
What symptoms would you expect to observe in an individual who has damage to the basal nuclei? damage to the basal nuclei would result in decreased muscle tone and the loss of coordination of learned movement patterns. A patient suffers a head injury that damages her primary motor cortex.
Can you recover from basal ganglia damage?
Your short-term and long-term outlook after a basal ganglia stroke depends on how quickly you were treated and how many neurons were lost. The brain can sometimes recover from injury, but it will take time. Be patient and work closely with your healthcare team to take steps toward recovery.
What is between the thalamus and putamen?
(B) Cell bridges between the caudate and putamen give a striated appearance. The subthalamic nucleus is part of the diencephalon; as its name implies, it is located just below the thalamus. The substantia nigra is a midbrain structure, composed of two distinct parts: the pars compacta and the pars reticulata.

Is the putamen a common site of cerebral hemorrhage?
The putamen is a common site of hypertensive cerebral hemorrhage. Such hemorrhages show a large range of possible presentations – from enormous hemorrhages involving the white matter of the hemispheres and the ventricular system, to cases occurring without causing any symptoms or neurological signs. …
What is a basal ganglia hemorrhage?
The basal ganglia are a common site for hypertensive hemorrhage, which forms part of the spectrum of stroke.
What is the pathophysiology of bilateral putaminal hemorrhage in methanol toxicity?
Bilateral putaminal hemorrhages, complication carrying very high morbidity, have been described in methanol intoxication and can be found in other diseases including inborn error metabolism, renal failure with severe metabolic acidosis, and ethylene glycol intoxication.[1,2] The proposed underlying mechanism is acid-induced neural cell death.[3]
