Editor-in-Chief Hubert Fernandez

Featuring basic and clinical research contributing to the understanding, diagnosis, and treatment of all neurodegenerative syndromes in which parkinsonism, essential tremor, or related movement disorders may be a feature. IAPRD members receive complimentary access.

Clinical Parkinsonism & Related Disorders

New companion journal to PRD

Editors-in-Chief Huifang Shang and Daniel Truong

An online-only, open-access journal committed to publishing high-quality peer-reviewed articles related to clinical aspects of movement disorders, including treatment, investigative reports, and phenomenology.

Featured articles in PRD and CPRD journals

Is there more than one Parkinson’s disease? The authors suggest that the initial pathology starts either in the olfactory bulb or amygdala leading to a brain-first subtype, or in the enteric nervous system leading to a body-first subtype. They review recent original human studies including molecular imaging, structural imaging, clinical and pathological studies and assess their concordance with this model.

With recent partial positive results of anti-amyloid treatment in Alzheimer’s disease, classically defined as a tauopathy, should we consider combining anti – protein immunotherapies? Read more to better understand this topic, which could be the therapy of the future.

The majority of cervical dystonia (CD) are classified as idiopathic, with essentially normal brain imaging. However, dystonia can also be seen in various paraneoplastic disorders. In this study, the authors compare multiple blood based immune measures between idiopathic CD patients and controls.

Congratulations to the IAPRD 2024 Young Investigator Award Winners

Winners will present their studies at the 28th IAPRD Congress in Chicago, 13-16 May 2023 Mead, WA – May 10, 2023: The International Association of Parkinsonism and Related Disorders (IAPRD) recognizes three Young Investigators for their outstanding research in the field:

“These young investigators are performing cutting-edge research in Parkinson’s disease and dystonia that we are pleased to showcase at our Chicago meeting,” noted Dr. Mary Ann Chapman, Executive Director of the IAPRD.

Dr. Lin will present the results of her large cohort study of the AOPEP gene, a novel causative gene of autosomal recessive dystonia. Dystonia is a neurological condition of involuntary muscular contractions that lead to repetitive or twisting movements often of the neck or limbs. Mr. Royton will present the results of his study on postural control in Parkinson’s disease, focusing on the staging of postural control changes over the course of the disease. Dr. Torres Ballesteros will describe the results of her study on deep brain stimulation in Parkinson’s disease, and specifically the use of image-guided programming to help improve patient responses.

The International Association of Parkinsonism and Related Disorders (IAPRD) is a non-profit professional association dedicated to promoting education and research in parkinsonism and related disorders. The IAPRD’s 28th World Congress will take place in Chicago at the McCormick Place Congress Center from 13-16 May 2023. Visit for more information.
