• Renal Artery Stenosis

  There was no evidence of renal artery stenosis or adrenal tumor. Blood pressure was controlled with medication for a period of 6 months, and the patient was also given anticonvulsive therapy. [em-consulte.com]

• Hyperreflexia

  Interruption of corticospinal fibers rostral to the motor (pyramidal) decussation causes impairment of movement in the opposite body-half, which is especially severe in the arm and leg and is characterized by muscular weakness, spasticity and hyperreflexia [medical-dictionary.thefreedictionary.com]

  Symptoms include an increase in the muscle tone in the lower extremities, hyperreflexia, positive Babinski and a decrease in fine motor coordination. [sideeffects.embl.de]

  On exam there is a combined deficit of vibration and proprioception with pyramidal signs (plantar extension and hyperreflexia). [forums.studentdoctor.net]

  There is hypertonia (increased muscle tone, stiffness), hyperreflexia (exaggerated reflexes), and an oscillatory movement known as clonus. [courses.washington.edu]

• Clonus

  In a patient with clonus, a muscle stretch elicits alternating contractions of agonist and antagonist muscle groups. [courses.washington.edu]

  In a few days to a few weeks, flaccidity gradually gives way to spasticity at the same time that the tendon reflexes reappear and eventually become hyperactive, as indicated by foot clonus and Hoffmann’s sign 17. [jneurology.com]

  Primary lateral sclerosis The age of onset for primary lateral sclerosis (PLS) is usually between 40 and 60 years, with spasticity in the legs accompanied by hyperactive deep tendon reflexes, clonus, and Babinski sign. [emedicine.medscape.com]

Patients who have sustained damage to their corticospinal tract have a prognosis that varies, depending on the nature of the damage. Some patients may be able to regain motor control over the course of the healing process. [wisegeek.org]

This distinction is important for genetic counseling of family members and for the patient’s prognosis, in that HSP generally carries a more favorable prognosis. [2] Other components of the differential diagnosis of HSP are similar to those of PLS. [emedicine.medscape.com]
