Previous prognostic studies investigating WD were primarily focused on the pyramidal tracts and, due to the limitation of rare occurrence, there have been only a few studies investigating the prognosis of WD of MCPs.
However, the pyramidal tract cannot affect the cognitive function, because it is a pathway for motor neurons.
It still represents a minimal but mostly important sign to be performed when suspecting a lesion of the pyramidal tract, e.g.

This means that unilateral pyramidal tract lesions above the point of decussation in the pyramids will cause paralysis of the muscles served by the spinal nerves on the opposite side of the body.
The pyramidal tract was found in 61% of all operated patients, so it can be considered as a normal component of the thyroid gland and not as ectopic tissue.
In addition, the ataxia is correlated with the extent of olivopontine atrophy while pyramidal signs are often associated with degeneration of the pyramidal tract. Several of the brain areas affected in MSA are involved in visual function including areas of the cerebral cortex, striatum, midbrain, and cerebellum.
Intraoperative diffusion-weighted imaging using an intraoperative MR scanner of low magnetic field strength (0.3 Tesla) has been developed demonstrating clinical usefulness and efficacy in detecting the pyramidal tract and its relationship with tumor borders [26].
the Babinski sign) is indicative of corticospinal or pyramidal tract dysfunction in the adult.
But in older children and adults, the presence of the reflex may be an indication of damage to nerve pathways that connect the brain and the spinal cord, in an area called the pyramidal tract. The reflex response may be an indication that head or spinal cord injuries, amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease), stroke, meningitis, or other neurologic problems may be present.
There was no pyramidal tract, sensory or cerebellar signs and his gait was also normal.
