In this video, one can appreciate that the patient has a lower motor neuron type of weakness affecting the right facial nerve. On asking the patient to look upwards (stimulation of the frontalis muscles), one can appreciate the lack of wrinkles over the forehead on the right side compared with the left. On asking the…

There are a number of ways of classifying ischaemic stroke. One of them is by anatomical classification e.g. anterior versus posterior circulation, the precise artery involved (e.g. left middle cerebral artery infarction) or the structure affected (e.g. right pontine infarct). It can also be classified according to the underlying etiology. A commonly used classification system is the TOAST…

Muscle wasting (or atrophy) is due to denervation of the muscle supplied by the motor nerve and occurs in lower motor…
