  • Causes In primary lateral sclerosis ( PLS ), the nerve cells in the brain that control movement fail over time. This loss causes movement problems, such as slow movements, balance problems and clumsiness.[mayoclinic.org]
  • Over time, your muscles waste away. You may hear a doctor or nurse call this “atrophy.” When this happens, you lose control over movements. It gets harder to walk, talk, swallow, and breathe.[webmd.com]

  • When the motor neurons can no longer send impulses to the muscles, the muscles begin to waste away (atrophy), causing increased muscle weakness.[hopkinsmedicine.org]

  • Breathing may also become compromised in the later stages of the disease, causing those patients who develop ventilatory failure to require noninvasive ventilatory support. [3] Hyperreflexia is another key feature of PLS as seen in patients presenting[en.wikipedia.org]
Babinski Sign
  • There are no standard laboratory tests for upper motor neuron disease, but spasticity (a specific type of stiffness), abnormally brisk tendon reflexes, Babinski’s sign and diminished fine motor coordination are seen as diagnostic signs on examination.[memory.ucsf.edu]
  • sign . [4] Some people present with emotional lability and bladder urgency, [4] and occasionally people with PLS experience mild cognitive changes detectable on neuropsychological testing , particularly on measures of executive function . [5] PLS is[en.wikipedia.org]
  • Lower motor neuron loss causes initially increased electrical excitability leading to fasciculations, and later muscle weakness and atrophy; upper motor neuron involvement causes spasticity, clonus, hyperactive tendon reflexes, and Babinski signs.[neuropathology-web.org]
  • Ankle clonus and Babinsky signs were elicited bilaterally. Lumbar puncture was negative for oligoclonal bands. Results MR mages were acquired on a Magnetom Sonata 1.5T scanner (Siemens, Erlangen, Germany).[ajnr.org]
  • Signs of upper motor neuron dysfunction may include limb and trunk spasticity, pathologic spread of deep tendon reflexes, clonus, pathologic reflexes (such as Babinski's sign), and spastic dysarthria.[dynamicchiropractic.com]
Spastic Gait
  • He slowly developed a progressive spastic gait, to the point that a recent fall last year required percutaneous pinning and plating for a right ankle fracture. He takes no medications.[dynamicchiropractic.com]

  • Pure primary lateral sclerosis and UMN-dominant ALS appear to have a more benign prognosis than typical ALS. Survival for patients with UMN-dominant ALS was intermediate between that of primary lateral sclerosis and classic ALS.[pallipedia.org]
  • In 21 people with muscular atrophy in only specific parts of the arm, for more than four years, the prognosis was good: they were likely to survive for many years with little deterioration of muscle function.[alzforum.org]
  • This cautious approach is understandable, given the prognosis of the illness and the devastation that being given the diagnosis may cause to a person's life.[patient.info]
  • (See Prognosis and Treatment.) The slow rate of progression of PLS provides most patients and families with time to adapt to the changes and identify resources for support.[emedicine.medscape.com]
