Bradykinesia:slowed movement on medication

What does bradykinesia feel like?

Bradykinesia can creep up so gradually that other people notice it first. People describe feeling slow and heavy on their medication, or that their body is running at half speed. Common signs include:

• Walking more slowly, with shorter or shuffling steps
• Arms that swing less when walking
• Fiddly tasks, like doing up buttons or typing, taking longer
• Handwriting that becomes smaller
• A face that shows less expression
• A voice that sounds softer or flatter than usual
• Finding it hard to get started, such as getting up from a chair

What causes slowed movement on medication?

Antipsychotic medications that block dopamine can slow the brain signals that start and scale movement. The result can be movements that are slower, smaller and harder to begin.

Bradykinesia is usually one part of drug-induced parkinsonism, a pattern that can also include muscle stiffness and tremor. It tends to develop over weeks to months after starting a medicine or increasing the dose.

What is drug-induced parkinsonism?

Drug-induced parkinsonism, also called pseudoparkinsonism, is a group of movement side effects that look like Parkinson's disease but are caused by a medicine. It usually means some combination of slowed movement, muscle stiffness and tremor. It is a side effect rather than a disease of the brain, and it often eases once a doctor adjusts the medicine or the plan around it, although this differs between people.

Is it bradykinesia, tiredness or low mood?

These can be hard to tell apart. Some medicines make people drowsy, and depression itself can make thinking and moving feel slower. Bradykinesia is more about the movements themselves becoming slow, small and hard to start, even when you feel awake and want to move.

Only a doctor can tell what is behind it, and the differences matter for what happens next. Describing what you notice, and asking someone close to you what they have seen, helps.

How do I describe slowed movement to my doctor?

Comparing now with a normal day before the change is often the clearest way. Try to cover:

• When you first noticed moving more slowly, and any medication or dose change around then
• Everyday tasks that now take longer, and roughly how much longer
• Whether you also feel stiff or shaky
• Whether you feel sleepy or low, or awake but slow
• What family, friends or carers have noticed

Should I stop my medication if I notice slowed movement?

No. Do not stop or change a medication on your own, even if you think it is causing slowed movement. Stopping suddenly can bring back the symptoms the medicine was prescribed for, or cause other effects. Contact your doctor or care team, tell them what you have noticed, and decide on next steps together. Movement side effects are well recognised, and there are usually options to talk through.

How to keep track of slowed movement with EPSpeak

EPSpeak lets you log your medications and doses, complete a short daily voice and wellness check-in, and note in your own words how your body feels. Your check-ins build into a history over days and weeks, which makes slow, gradual change easier to see and to describe.

EPSpeak does not diagnose bradykinesia or any other condition. Its voice score compares each recording with your own earlier recordings, and it does not say why anything changed. You can share your record with a clinician using a QR code.
