classic triad for early Parkinsons?

resting tremor

no weakness
Intention/kinetic tremors are due to damage to:
the cerebellum

Damage to thalamus is likely to produce a (deficiency):
sensory disturbance
nystagmus with a slow component to the left and a fast component to the right is called a
right beating nystagmus.
A downbeating nystagmus can be produced by:
a lesion at the cervicomedullary junction, such as a meningioma at the foramen magnum
Abnormal Heal-to-toe walking / Tandem gait may be because of
Cerebellar dysfunction

routine test for alcahol intoxication
(however, weakness, vertigo, etc can also contribute to it)
Anisocoria is
unequal size of the pupils
ptosis + miosis indicates which disease:
oculosympathetic palsy (Horner's syndrome)
Sympathetic nerve pathway to to the eye
hypothalamus --> down through lateral aspect of brainstem --> synapses in the intermediolateral cell column of the spinal cord --> exits the spinal cord at T1 and synapses again in the suprerior cervical ganglion --> post ganglionic fibers travel along surface of COMMON CAROTID and INTERNAL CAROTID until branches leave along the opthalmic artery to the eye

Acute Horners is often <-- carotid artery dissection
