Adverse Events

The following is a list of known risks with the use of deep brain stimulation. Note that some of these
symptoms may be resolved or reduced by current steering, changing stimulation parameters, or by
changing the position of the lead during surgery.
If any of these events occur, patients should inform their physician as soon as possible.
Allergic or immune system response
Anesthesia/neurosurgery risks, including unsuccessful implant, exposure to bloodborne
pathogens
CSF leak
Death, including suicide
Embolism, including air embolism and pulmonary embolism
Failure or malfunction of any of the device components or the battery, including but
not limited to lead or extension breakage, hardware malfunctions, loose connections,
electrical shorts or open circuits and lead insulation breaches, whether or not this
requires explant and/or reimplantion
Hemorrhagic or ischemic stroke, immediate or delayed, which could result in temporary
or permanent neurologic deficits such as muscle weakness, paralysis or aphasia
Implant site complications such as pain, poor healing, wound reopening
Infection
Injury to tissues adjacent to implant or within surgical field, such as blood vessels,
peripheral nerves, brain (including pneumocephalus), or pleura (including
pneumothorax).
Interference from external electromagnetic sources
Lead, extension (including extension header) and neurostimulator erosion or migration
Loss of adequate stimulation
Mentation impairment such as attention or cognitive deficits, memory disturbances, or
confusion
Psychiatric disturbances such as anxiety, depression, apathy, mania, insomnia, suicide,
or suicidal ideation or attempts
Motor problems such as paresis, weakness, incoordination, restlessness, muscle
spasms, postural and gait disorders, tremor, dystonia, or dyskinesias, and falls or injuries
resulting from these problems
Musculoskeletal stiffness
Neuroleptic malignant syndrome or acute akinesia can occur very rarely
Overstimulation or undesirable sensations, such as paresthesia, transient or persistent
