Clinical Trial Summary

Popular science summary of the project The purpose of the study is to investigate in a Swedish population how well the investigators' previous ultrasound findings match the final diagnosis (PD, APS or ET) after a particularly long follow-up time, which greatly increases the certainty that the diagnosis does not change more and is thus correct. Furthermore, the investigators want to study whether the initial ultrasound findings have changed during the control interval and whether measurement results regarding the diameter in one of the fluid-filled rooms in the brain (third ventricle) can be correlated with the development of cognitive impairment or dementia later in the course of the disease. For this, this study have got ethical permission to go into the patients' medical records and to call a subgroup back to the clinic to be able to do a new examination and a memory test.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Correlation	Is hyperechogenicity of substantia nigra at mesencephal plane (measured bilaterally in mm2 by transcranial b-mode sonography correlated with a high percentage of patients with classical Parkinsons Disease in contrast to atypical parkinsonism patients?	over 7-10 yrs
Secondary	Correlation	Is 3rd ventricle atrophy (measured in mm by b-mode transcranial sonography) correlated with a high % of demented patients in the cohort?	7-10 (retrospective)
