Parkinsonian Syndrome


  • In the present study, the sensitivity for the diagnosis of PSP was 84.2%.[academic.oup.com]

  • In the present study, the NPR was available from 1964 to 2009.[karger.com]
  • Atypical Parkinsonian disorders are progressive diseases that present with some of the signs and symptoms of Parkinson’s disease, but that generally do not respond well to drug treatment with levodopa.[hopkinsmedicine.org]
  • Since SPGR images are more widely available and faster to acquire than DTI, we focus on these for the present work.[journals.plos.org]
  • Backward falls are common and may occur during the early course of the disease. PSP is not usually associated with tremor, unlike Parkinson’s disease.[hopkinsmedicine.org]

  • As dopamine levels fall in a person with PD, their symptoms gradually become more severe.[medicalnewstoday.com]
  • Such balance problems in Parkinson’s disease are associated with a tendency to list or fall backward (retropulsion); in fact, a light push can cause the individual with Parkinson’s disease to continue stepping backward or to even fall down.[apdaparkinson.org]
  • Women who complained of fatigue and sleepiness were more often diagnosed with depression than sleep apnea.[clinicaladvisor.com]
  • Fatigue Fatigue is a complex symptom of Parkinson’s disease that is not fully understood. It is known, however, that fatigue is significantly associated with depression and sleep disorders.[apdaparkinson.org]
  • Fatigue. Many people with Parkinson's disease lose energy and experience fatigue, especially later in the day. The cause isn't always known. Pain.[mayoclinic.org]

Mask-like Facies
  • […] characterized by insidious onset of rhythmical muscular tremors at rest (pill-rolling tremor; 4–6 Hz), paucity and slowness of movement (hypokinesia, bradykinesia) and generalized rigidity (cogwheel and lead-pipe rigidity), festinant gait, stooped posture, mask-like[medical-dictionary.thefreedictionary.com]
  • In addition to a general slowness of movement, the bradykinesia of Parkinson’s disease is typically demonstrated by a reduced or mask-like expression of the face (hypomimia or facial masking), a decreased blink rate of the eyes, and problems with fine[apdaparkinson.org]
Facial Muscle Rigidity
  • Facial muscle rigidity can also partly or completely account for the "masked facies."[dartmouth.edu]
  • The tremor (shaking body parts) of Parkinson disease appears during rest of the limb and disappears or weakens during active movement. Additionally, Parkinson's disease cause walking problems and slow movements.[medical-dictionary.thefreedictionary.com]
  • PSP is not usually associated with tremor, unlike Parkinson’s disease.[hopkinsmedicine.org]
  • We found that clinical presentation (presence of tremor-dominant disease) did not seem to affect disease detection in the NPR.[karger.com]
  • The tremors are usually rhythmic or pendulous in nature. Essential tremor usually affects the hands and feet, but voice tremors and head tremors are also seen. The condition may be severely disabling in the long term.[news-medical.net]
  • […] certain antipsychotic drugs (e.g. perazine, phenothiazines, butyrophenones and depot preparations); characterized by insidious onset of rhythmical muscular tremors at rest (pill-rolling tremor; 4–6 Hz), paucity and slowness of movement (hypokinesia, bradykinesia[medical-dictionary.thefreedictionary.com]
  • Bradykinesia Greek for “slow movement,” bradykinesia is a frequent symptom of Parkinson’s disease and related movement disorders.[apdaparkinson.org]
  • Bradykinesia and rigidity are additive in hindering movement and are usually present together. Bradykinesia is, however, not dependent on or necessarily proportional to rigidity, and vice versa.[dartmouth.edu]
  • Subtle “bradykinesia” has been reported to occur in the “normal elderly” population, but this may reflect a non-specific slowness rather than bradykinesia as defined above.[movementdisorders.org]
Postural Instability
  • Postural Instability More pronounced in the later stages, postural instability includes the inability to maintain a steady, upright posture or to prevent a fall.[apdaparkinson.org]

  • Can cause problems with slowness, shuffling gait and thinking problems. Head CT or MRI may be helpful in determining this.[nwpf.org]
  • Parkinson’s disease is characterized by rigidity of muscles, facial immobility, tremors and a shortened “shufflinggait. Eventually, the patient may be unable to cope with ADL and may have to depend on a caregiver.[news-medical.net]
  • They may also develop a shuffling gait. Facial expression : This can become fixed, due to changes in the nerves that control facial muscles. Voice : There may be a tremor in the voice, or the person may speak more softly than before.[medicalnewstoday.com]
  • Later, steps may become slow and small, and a shuffling gait (festination) may appear. Gait problems in Parkinson’s disease can also include a tendency to propel forward with rapid, short steps (propulsion).[apdaparkinson.org]
