What is the Difference Between Bradykinesia and Hypokinesia?

🆚 Go to Comparative Table 🆚

Bradykinesia and hypokinesia are both motor disorders associated with Parkinson's disease and other conditions, but they have distinct characteristics:

  • Bradykinesia refers to a slowed speed of movement. It is a symptom of Parkinson's disease and can also be a side effect of certain medications. Bradykinesia can range from mild slowing of movement to complete immobility, depending on the severity of the condition.
  • Hypokinesia indicates a reduced amplitude of movement. It is often considered a part of bradykinesia and can be a symptom of diseases such as Parkinson's disease, schizophrenia, dementia with Lewy bodies, multiple system atrophy, progressive supranuclear palsy, stroke, and cortical basal ganglionic degeneration. Hypokinesia is characterized by movements that are not as wide-ranging as they normally should be.

In summary, the key difference between bradykinesia and hypokinesia is that bradykinesia involves a slowed speed of movement, while hypokinesia involves a reduced amplitude of movement. Both conditions are often associated with Parkinson's disease and other motor disorders.

    Here is a table comparing the differences between bradykinesia and hypokinesia:

    Feature Bradykinesia Hypokinesia
    Definition Slowness of movement Reduced amplitude of movement
    Description Involves decreased speed of voluntary movements Involves decreased amplitude of voluntary movements, often characterized by smaller movements
    Causes Associated with Parkinson's disease, certain medications, and other conditions that affect the basal ganglia Can be present as a symptom of Parkinson's disease, schizophrenia, dementia with Lewy bodies, multiple system atrophy, progressive supranuclear palsy, stroke, and cortical basal ganglionic degeneration
    Treatment Bradykinesia in Parkinson's disease may improve with levodopa therapy Hypokinesia in Parkinson's disease may also improve with levodopa therapy, but other causes may require different treatments

    Both bradykinesia and hypokinesia are motor diseases associated with Parkinson's disease and other conditions that affect the basal ganglia. Sometimes, hypokinesia is considered a part of bradykinesia.
