- Background: CSF concentration of neurogranin has been suggested as a biomarker for synapse dysfunction. Objectives: To investigate CSF neurogranin in parkinsonian disorders compared to controls and Alzheimer's disease and the possible correlations between neurogranin and cognitive and motor impairment. Methods: We included 157 patients with PD, 29 with PD with dementia, 11 with dementia with Lewy bodies, 26 with MSA, 21 with PSP, 6 with corticobasal syndrome, 47 controls, and 124 with Alzheimer's disease. CSF neurogranin was measured using two enzyme-linked immunosorbent assays; from EUROIMMUN and the University of Gothenburg. Results: We found a strong correlation between CSF neurogranin-EI and CSF neurogranin–University of Gothenburg (Rs = 0.890; P < 0.001). Neurogranin was decreased in PD, PD with dementia, MSA, and PSP compared to controls and Alzheimer's disease. Neurogranin did not correlate with motor or cognitive impairment, longitudinal decline, or progression to dementia in PD. Conclusions: CSF neurogranin is decreased in parkinsonian disorders compared to controls, emphasizing the importance of synaptic dysfunction in these disorders.

- The purpose of this study was to investigate whether cerebrospinal fluid (CSF) levels of tau, phosphorylated tau, β-amyloid42 , α-synuclein, neurofilament light, and YKL-40 change over time and if changes correlate with motor progression and/or cognitive decline in patients with PD and controls.

- Background: Alzheimer's disease co-pathology is common in dementia with Lewy bodies and Parkinson's disease with dementia (Lewy body disease) and can reliably be detected with positron emission tomography (PET) or cerebrospinal fluid (CSF) biomarkers. Recently developed blood biomarkers are more accessible and less expensive alternatives. Objective: To investigate if plasma phospho-tau217 and phospho-tau181 can detect Alzheimer's pathology in Lewy body disease with dementia. Methods: In this cross-sectional study we investigated plasma phospho-tau217 and phospho-tau181 in 35 patients with Lewy body disease with dementia. Patients underwent tau-PET imaging (18F-RO948). Results: Plasma phospho-tau217 correlated with plasma phospho-tau181, CSF phospho-tau217 (rs = 0.68, P < 0.001), and negatively with CSF β-amyloid42/40 (rs = −0.52, P = 0.001). Plasma phospho-tau217 and phospho-tau181 correlated with tau-PET signal in the temporal cortex (rs > 0.56, P < 0.001) and predicted abnormal tau-PET status and β-amyloid status (area under the curve > 0.78 and > 0.81, respectively). Conclusion: Plasma phospho-tau might be a useful marker for Alzheimer's co-pathology in Lewy body disease with dementia.

Assessment of ability/disability in patients treated with chronic thalamic stimulation for tremor.

- Chronic thalamic stimulation (CTS) has a documented good effect on tremor in patients with Parkinson's disease (PD) and essential tremor (ET). This study evaluates whether the alleviation of impairment, i.e., tremor, translates into improvement of the patient's ability in performing instrumental activities of daily living (IADL). Thirteen patients were assessed with an occupational therapy tool called Assessment of Motor and Process Skills (AMPS). This observation-based scale rates the patient's motor and process skills needed to perform a given task. The evaluations were done at a mean of 13 months after surgery in the patient's home, and included assessments of IADL with the CTS activated and switched off, respectively. The results showed that most patients improved to variable degrees in their IADL ability when the thalamic stimulation was on. The improvement was more marked in patients operated on for tremor of their dominant hand. The improvement concerned mainly the skill items related to the patients' abilities of coordination, calibration, endurance, and accommodation during IADL task performance. The authors concluded that for some patients with tremor, CTS can improve independence in domestic activities of daily living.

- We evaluated the impact of pallidotomy and thalamic deep brain stimulation (DBS) on disability of patients with advanced Parkinson's disease and investigated whether the activities of daily living (ADL) section of the Unified Parkinson's Disease Rating Scale (UPDRS) measures disability in everyday life. Nineteen patients who had pallidotomy and 14 patients who had thalamic DBS were followed for a mean of 11 months. Evaluation tools included the UPDRS as well as a generic ADL scale, called ADL taxonomy. The 13 items belonging to the ADL part of the UPDRS were classified into two categories according to whether the items described a disability or impairment. The total scores of the UPDRS Part II (ADL) were ameliorated in both the pallidotomy and the thalamic DBS groups. When analysing separately the scores from the two categories of the ADL part of the UPDRS, i.e., disability and impairment, only patients who underwent pallidotomy showed improvement in disability-related items. These findings were confirmed when evaluating the patients with the ADL taxonomy. The ADL part of the UPDRS contains a mixture of impairment- and disability-related items. This mixture may confound results when evaluating the impact of surgery on ADL.

Patients' perceptions of life shift after deep brain stimulation for primary dystonia : a qualitative study

- Studies of deep brain stimulation for dystonia have shown significant motor improvement. However, patients' perceptions of surgery and its effects have been less studied. We aimed to explore perceptions of changes in life in patients with primary dystonia after deep brain stimulation. Thirteen patients underwent thematic interviews 8-60 months after pallidal deep brain stimulation. Interviews were transcribed verbatim and analyzed with grounded theory. Patients described a profound impact of dystonia on daily life. After surgery, physical changes with a more upright posture and fewer spasms translated into an easier, more satisfying life with greater confidence. Notwithstanding this positive outcome, the transition from a limited life before surgery to opportunities for a better life exhibited obstacles: The "new life" after deep brain stimulation was stressful, including concern about being dependent on the stimulator as well as having to deal with interfering side effects from deep brain stimulation. The whole coping process meant that patients had to quickly shift focus from struggling to adapt to a slowly progressive disorder to adjustment to a life with possibilities, but also with new challenges. In this demanding transition process, patients wished to be offered better professional guidance and support. Even though deep brain stimulation provides people with primary dystonia with a potential for better mobility and more confidence, patients experienced new challenges and expressed the need for support and counseling after surgery. Grounded theory is a useful method to highlight patients' own experience and contributes to a deeper understanding of the impact of deep brain stimulation on patients with dystonia.
