447 Possible Causes for Pyramidal Tract Signs

  • Acute Transverse Myelitis

    Flaccid weakness gradually changes to pyramidal tract signs, with hyperreflexia, clonus, and extensor responses.[]

  • Pallidopyramidal Syndrome

    […] of early-onset, progressive parkinsonism with pyramidal tract signs has been known as pallido-pyramidal or parkinsonian-pyramidal syndrome since the first description by[] Abstract Background: The combination of early-onset, progressive parkinsonism with pyramidal tract signs has been known as pallido-pyramidal or parkinsonian-pyramidal syndrome[] […] symptoms and pyramidal tract signs.[]

  • Hereditary ATTR Amyloidosis

    Furuya H et al. (1987) Molecular analysis of a variant type of familial amyloidotic polyneuropathy showing cerebellar ataxia and pyramidal tract signs. [ ] 23.[]

  • Hereditary Spastic Paraplegia

    We present three patients with complicated HSP from two unrelated families, who had early onset progressive cerebellar signs and developed pyramidal tract signs during follow-up[] tract dysfunction.[] In view of their known functional role, damage to these central nervous gray and white matter components offers explanations for the patient's pyramidal signs, her cerebellar[]

  • Pyramidal Tract Lesion

    Babinski sign in absence of Pyramidal Tract Lesion can occur in physiological and pathological conditions Physiological causes of Babinski sign in absence of Pyramidal Tract[] Neurological examination revealed bilateral pyramidal-tract signs, and paresis of the right arm.[] I always thought a singular lesion in pyramidal tract would only cause Babiniski sign and loss of superficial reflexes.[]

  • Sterol 27-Hydroxylase Deficiency

    tract signs, cerebellar ataxia, and mental retardation. 1 The pathogenesis is linked to genetic alterations in the mitochondrial sterol 27-hydroxylase gene ( CYP27 ) that[] The characteristic neurological features often leading to diagnosis in the second or third decade of life are pyramidal tract signs, cerebellar syndrome, peripheral neuropathy[] Up to now in the literature, only seven adult CTX patients have been reported with predominant pyramidal signs, and the absence of both cerebellar signs and mental retardation[]

  • Upper Motor Neuron Disease

    Increased deep tendon reflex (DTR) Pronator drift [3] Corticospinal/pyramidal tract [ edit ] These are the neural tracts which descend in the ventral horn of the spinal cord[] The presence of the Babinski sign after 12 months is the sign of a non-specific upper motor neuron lesion.[]

  • Subacute Combined Degeneration of Spinal Cord

    Both patients showed clinical and electrophysiological damage to the posterior column and no signs of pyramidal tract involvement.[] A midline lesion of the medulla oblongata is likely to involve the pyramidal tracts (the descending motor pathway) and the medial lemnisci (the ascending tracts relaying sensory[] tract damage was graded as 1 positive Babinski sign, 2 spastic paraparesis, or 3 spastic tetraparesis.[]

  • Spastic Paraplegia

    In addition to pure forms, in which symptoms are limited to lower limb pyramidal tract dysfunction, complicated forms exist with additional neurological signs and usually[] The main feature of the disease is progressive spasticity in the lower limbs due to pyramidal tract dysfunction.[] The term hereditary spastic paraplegia was coined by Anita Harding in 1983. [9] Signs and symptoms [ edit ] Symptoms depend on the type of HSP inherited.[]

  • Thoracic Spinal Cord Tumor

    Weakness is due to the involvement of the pyramidal or corticospinal tract. The degree of motor impairment may range from clumsiness to complete quadriplegia.[] Myelopathy may be evident with central spinal cord tumors, resulting in spasticity, paresis, hyperactive reflexes, Babinski’s sign.[]
