Question 1
In this movement disorder, excessive or inappropriate contraction of muscles (often agonists and antagonists) leads to sustained abnormal postures of the affected region of the body. The abnormal movements and postures may be generalized (involving the trunk and at least two other sites) or restricted in distribution, such as to the neck, hand and forearm, or mouth.
Question 2
Small vessel occlusion affecting penetrating arteries deep in the brain may cause infarcts in the putamen, thalamus, caudate nucleus, pons, posterior limb of the internal capsule, or other sites. These are rarely fatal but may be noted at autopsy. They are referred to as
Question 3
A person who does not know who and where he or she is and the approximate date or time is said to be
Question 4
The sudden onset of "the worst headache I've ever had in my life" is classically due to
Question 5
Two contraindications for a lumbar puncture are
1.dysyonias
These are abnormal movement disorder caused by sustained contraction of a particular muscle group. These may be idiopathic or secondary to drugs like antipsychotic medication.
Chorea and athetosis are less severe and in those rapid movement occurs but no sustained contraction.
Asterexis is a sign seen in hepatic encephalopathy
2. Lacunar infarcts
These are small infarcts in the deeper brain structures due to the occlusion of the small vessels. This occurs mostly secondary to atherosclerosis.
Dissection infarcts occits due to vessel dissection and involves a large area
Moyamoya disease is due to carotid vessel pathology and it mainly involve the basal ganglia
3. Disoriented
A person who is disoriented can't know their place or time of location and their orientation to the surroundings are lost
Stupor is near coma where a patient can't be responded until a severe painful stimuli
Amnesia means loss of memory
4. Subarachnoid hemorrhage
It always presents with severe headache and is often called by the patients - worst headache of my life
5. Caogulopathy and raised ICT
Lumbar puncture is contraindicated in caogulopathy which causes excessive bleeding and in raised ICT where lumbar puncture can causes sudden pressure drop and can lead to brainstem herniation
Hope this helps... Thank you!!!
