Identifying Decision Points for Safe and Interpretable Reinforcement Learning in Hypotension Treatment [PDF]
arXiv, 2021 Many batch RL health applications first discretize time into fixed intervals. However, this discretization both loses resolution and forces a policy computation at each (potentially fine) interval. In this work, we develop a novel framework to compress continuous trajectories into a few, interpretable decision points --places where the batch data ...

European Journal of Neurology, Volume 30, Issue 1, Page 96-106, January 2023., 2023 Abstract Background and purpose Treatment of freezing of gait (FoG) and other Parkinson disease (PD) axial symptoms is challenging. Systematic assessments of axial symptoms at progressively increasing levodopa doses are lacking. We sought to analyze the resistance to high levodopa doses of FoG, posture, speech, and altered gait features presenting in ...

Postural Orthostatic Tachycardia Syndrome explained using abaroreflex response model [PDF]
arXiv, 2021 Recent studies have shown that Postural Orthostatic Tachycardia Syndrome (POTS) patients have abnormal low frequency $\approx 0.1$ Hz blood pressure and heart rate dynamics. These dynamics are attributed to the baroreflex and can give insight into the mechanistic causes which are the basis for proposed subgroups of POTS.

Neurology, 2020 Objectives To assess the frequency of transient orthostatic hypotension (tOH) and its clinical impact in Parkinson disease (PD), we retrospectively studied 173 patients with PD and 173 age- and sex-matched controls with orthostatic intolerance, who ...

European Journal of Neurology, Volume 30, Issue 1, Page 235-240, January 2023., 2023 Cerebrospinal fluid (CSF) alterations indicative of infratentorial superficial siderosis are prevalent amongst patients with SIH. It is speculated that a preclinical phase without symptoms or imaging signs but during which elevated biomarkers of the disease are apparent from CSF analysis might exist.

Squamous Carcinoma of the Lung Presenting as Migraine-Type Headache: A Case Report
Case Reports in Oncology, 2015 Introduction: Orthostatic hypotension has long been recognised as a paraneoplastic effect of lung cancer. Lung cancer presenting with orthostatic hypotension and migraine-type headaches has not been previously described in the literature.

The management of orthostatic hypotension in Parkinson's disease
Frontiers in Neurology, 2013 Orthostatic hypotension is a common and disabling symptom affecting Parkinson’s disease (PD) patients. We present the effect of the different therapies commonly used to manage Parkinson’s disease on this clinical manifestation.

Orthostatic hypotension: An overlooked but clinically decisive entity
Journal of the Indian Academy of Geriatrics, 2022 Orthostatic hypotension (OH) is defined as a drop of >20 mm Hg of systolic or >10 mm Hg of diastolic blood pressure (BP) within 3 min of standing from lying position. It is a common geriatric syndrome caused by impaired orthostatic response of BP.

Journal of the Peripheral Nervous System, Volume 27, Issue 4, Page 325-329, December 2022., 2022 Abstract Small fiber neuropathy usually presents with gradual and progressive chronic length‐dependent pain. Acute small fiber neuropathy is rarely reported. Three patients with acute onset neuropathic pain after Oxford‐AstraZeneca ChAdOx1‐S vaccination are described.

Orthostatic Hypotension: A Prodromal Marker of Parkinson's Disease?
Movement Disorders, 2020 Orthostatic hypotension is common in patients with Parkinson's disease (PD). However, it remains unknown whether orthostatic hypotension is a marker of prodromal PD or more advanced disease. The objectives of this study were to assess whether orthostatic
