Many side effects of DBS are
usually mild and transient in nature, and can be managed non-invasively by
adjusting the stimulation parameters.
Side effects of DBS may include
the following:
- tingling sensation (paresthesia)
- worsening of symptoms
- speech problems (dysarthria, dysphasia )
- dizziness or lightheadedness (disequilibrium)
- facial and limb muscle weakness or partial
paralysis (paresis)
- abnormal, involuntary
muscle contractions (dystonia,
dyskinesia)
- movement problems or reduced coordination
- jolting or shocking sensation
- numbness (hypoesthesia).
Several follow-up visits may be
necessary in order to find the right stimulation settings to optimise symptom
control and minimise side effects.
Potential surgical risk
As with any surgery
there are some risks associated with the procedure
itself, but these are very low when DBS therapy is performed by an experienced
team.
Risks may include:
- intracranial hemorrhage
- leakage of cerebral fluid surrounding the
brain
- seizure
- infection
- allergic response to implanted materials
- temporary or permanent neurological
complications
- confusion or attention problems
- pain at the surgery sites
- headaches.
When
complications do occur in DBS, they are generally mild, short-lived and
normally resolve around 30–90 days after surgery.
Your doctor can provide more
information about these risks. Additional information can also be found in the
Medtronic DBS Therapy patient manual, available through the EPDA website (www.epda.eu.com/medInfo/dbs).
