  • These complications include infections, pneumonia, falls, and choking. With proper treatment, however, patients with Parkinson’s can live as long as those without the disease.[healthline.com]
  • It has been suggested that the difference in the disease progression between LBD and Alzheimer’s can partially be explained by the increase in falls, and therefore injuries and hospitalizations, in those with LBD.[verywell.com]
  • Repeated falls are common. Fluctuating cognitive function is a relatively specific feature of Lewy body dementia.[merckmanuals.com]
  • […] lunging forward when mobilizing. the other common early signs include general slowing of movement, change in personality and visual symptoms due to restricted eye movements especially in the vertical plane -because they can look down very well people fall[defeatparkinsons.com]

  • , it’s Parkinson’s, and if dementia appears before or at the same time as the tremors, it’s DLB.[qz.com]
  • Parkinson’s disease (PD) is characterized by motor symptoms, including resting tremor, stiffness, slowness, and walking/balance problems. The diagnosis of PD relies on the presence of slowness plus tremor and/or stiffness.[shakeitup.org.au]

Shuffling Gait
  • Over time most people with LBD develop a spectrum of problems that include great variations in attention and alertness from day to day, recurrent visual hallucinations, shuffling gait, tremors, and blank expression, along with various sleep disorders[disabled-world.com]
  • Other features include fluctuating cognition, visual hallucinations, and spontaneous features of Parkinsonism such as body stiffness, tremors, shuffling gait, emotionless facial features and/or decreased coordination.[medicinenet.com]
  • Reggie went on to develop a shuffling gait, and in 2006 a neurologist diagnosed Parkinson’s. Medication helped control those symptoms but in 2009 Reggie’s behaviour changed dramatically. ‘He became terribly aggressive,’ says Margaret.[dailymail.co.uk]
  • Some people may first show the motor symptoms of parkinsonism — slowness, stiffness in the muscles, tremors, decreased dexterity, or slow, shuffling gait. Others may have visual hallucinations as the first symptom.[caregiver.org]
  • Such symptoms can be provoked by distress and embarrassment over how others may react to seeing their Parkinson's tremor or shuffling gait, and the problem can hurt their ability to perform at work or enjoy social gatherings.[caring.com]
