====Caregivers====
More than half of caregivers rate DBS to the STN negatively at one year after surgery. Some of the symptoms caregivers were unhappy about included mania, apathy, depression, impulsivity, compulsivity, aggressiveness and disinhibition. Children of individuals with Parkinson's tended to be happier than spouses. Concerns raised by caregivers included dyskinesia impacting the [[physiognomy]] of their loved ones, leading to the inability to control movements and a glassy-eyed appearance. Family relationships changed between partners and children were also stressed because the empathy and self-awareness of patients diminished as they lost their sense of reality over time. The degree of dissatisfaction did not appear to correlate with the success of the surgery as far as motor symptoms, which generally improved.<ref>{{cite journal |last1=Cavallieri |first1=F |last2=Ghirotto |first2=L |title=Caregivers' burden and deep brain stimulation for Parkinson disease: A systematic review of qualitative studies. |journal=European Journal of Neurology |date=March 2024 |volume=31 |issue=3 |pages=e16149 |doi=10.1111/ene.16149 |pmid=37975788|pmc=11235895 }}</ref> Similar dissatisfaction persisted at two years in a separate analysis, with almost 60% of caregivers continuing to report dissatisfaction.<ref>{{cite journal |last1=van Hienen |first1=MM |last2=Contarino |first2=MF |last3=Middelkoop |first3=HAM |last4=van Hilten |first4=JJ |last5=Geraedts |first5=VJ |title=Effect of deep brain stimulation on caregivers of patients with Parkinson's disease: A systematic review. |journal=Parkinsonism & Related Disorders |date=December 2020 |volume=81 |pages=20–27 |doi=10.1016/j.parkreldis.2020.09.038 |pmid=33038702|hdl=1887/3249462 |hdl-access=free }}</ref>

Despite the high dissatisfaction rate of caregivers with surgery, additional measures such as caregiver burden, psychiatric and cognitive functioning and caregiver quality of life remained relatively stable. In addition, both patients and caregivers reported that they would opt for DBS again.<ref>{{cite journal |last1=van Hienen |first1=MM |last2=Contarino |first2=MF |title=Effect of deep brain stimulation on caregivers of patients with Parkinson's disease: A systematic review. |journal=Parkinsonism & Related Disorders |date=December 2020 |volume=81 |pages=20–27 |doi=10.1016/j.parkreldis.2020.09.038 |pmid=33038702|hdl=1887/3249462 |hdl-access=free }}</ref>
