The lectures and chapters from the book have been combined in a clear summary for the endterm. Here and there some Dutch bits have been added (green and italicized) so that it is also clear for Dutch students. Furthermore, many pictures have been used to illustrate and you will find more clear pict...

General history and physical exam
The general history and physical exam (H&P) usually contain the following elements:
• The chief complaint (CC)
• History of the present illness (HPI)
• Past medical history (PMH)
• Review of systems (ROS)
• Family history (FHx)
• Social and environmental history (SocHx/EnvHx)
• Medications and allergies
• Physical exam
• Laboratory data
• Assessment and plan
Hemiparesis vs. paralysis
Patient with stroke (infarction or hemorrhage bleeding): can have both a pure hemiparesis
or an paralysis. The stroke can both be a cortical as well as a subcortical problem
Pure hemiparesis: paralysis of one part of the body. Weakness of muscles (CNS problem)
(NL: verlamming van een kant van je lichaam)
• Pure hemiparesis with no sensory loss?
Then we can exclude some hypothesis, like:
o Cortical lesion: unlikely because a cortical lesion would involve the entire
motor strip (nearby sensory strip), therefore there is a high risk for sensory
involvement
(NL: hersenschors bedenkt veel kwabben, waaronder de hele motorstrip)
o Peripheral lesion: unlikely because the olfactory nerve and the opticus nerves
are peripheral, therefore the whole face would be affected as well as the
entire half of the body
(NL: hierbij zou het gezicht dus aangedaan moeten zijn)
o Medulla and the spinal cord are affected: unlikely because the face would be
spared and with pure hemiparesis half of the face is affected (only the lower
part of the face) The upper part of the face is controlled by the ipsilateral and
contralateral side. So, one side can take over the functions of the other side
(NL: als de medulla en ruggengraat geraakt zijn, is het gezicht ook vaak
aangetast)
o No sensory loss with pure hemiplegia is not very common
We can also include some areas:
o More likely to have sensory problems if you have a stroke near the motor
cortex, because the somatosensory cortex is nearby
So it could be in the following areas: this region motor systems come close together,
face also has bilateral branch so upper half will be ok
o Corticospinal/pyramidal tract (large motor systems) and corticobulbar
o Contralateral: on the other side
