and wide pulse widths should only be programmed
with due consideration of the warnings concerning
charge densities. The system can be programmed to
use parameter settings outside the range of those
used in the clinical studies. If the programming of
stimulation parameters exceeds the charge density
limit of 30 μC/cm2, a screen will appear warning you
that the charge density is too high. Charge density can
be reduced by lowering the stimulation amplitude or
pulse width. For more information, see the clinician
programmer manual.
Higher amplitudes and wider pulse widths may
indicate a system problem or a suboptimal lead
placement. Stimulation at high outputs may cause
unpleasant sensations or motor disturbances or may
render the patient incapable of controlling the patient
controller. If unpleasant sensations occur, the device
should be turned off immediately using the patient
magnet.
Risk of depression, suicidal ideations, and suicide.
Depression, suicidal ideation, and suicide have been
reported in patients receiving deep brain stimulation
therapy for movement disorders, although no direct
cause and effect relationship have been established.
Note the presence of any of the following symptoms
and discuss them with your clinician: depression,
suicidal thoughts, or behaviors, changes in mood, and
