The Swedish BioFINDER 2 Study

GENERAL AIMS: Develop methods for early and accurate diagnosis of different dementia disorders. This is important not only for the clinical diagnostic work-up, but also for selection of patients to clinical trials. Because dementia is very common among the elderly, but often misdiagnosed, we need to develop minimally invasive, reliable ...

Phase N/A

The Venous Distension Reflex and Orthostatic Hypertension

In humans, two-thirds of the blood volume is contained within the venous vasculature. Because of this, changes in peripheral blood volume and alterations in the mechanical properties of peripheral veins can greatly impact cardiac filling, cardiac output and blood pressure (BP) responses to physiologic stress. Work from our laboratory over ...

Effects of Melatonin to Reduce Nocturnal Hypertension in Patients With Neurogenic Orthostatic Hypotension

Neurogenic orthostatic hypotension (NOH) is a debilitating condition associated with reduced quality of life, impaired function and is also an independent predictor of mortality(Bendini et al., 2007; Cordeiro et al., 2009; Rose et al., 2006). NOH is clinically defined as a sustained reduction in systolic blood pressure (SBP) 30mmHg within ...

The Neural Basis for Frontotemporal Degeneration

Comparative and longitudinal studies reveal clinical differences between subgroups of patients with frontotemporal dementia (FTD), including Progressive Non-fluent Aphasia (PNFA), Semantic Dementia (SD), patients with a disorder of social comportment and personality (SOC), and non-aphasic patients with executive dysfunction (EXEC). MRI studies of cortical atrophy and fMRI studies show correlated ...

Phase N/A

Natural History Study of Synucleinopathies

-synuclein is a small protein of 140 amino acids that is highly expressed in the brain. It's function remains poorly understood.10 Synucleinopathies are a group of neurodegenerative diseases associated with the abnormal accumulation of -synuclein within cytoplasmic inclusions in neurons or oligodendroglia. These -synuclein containing cytoplasmic aggregates occur throughout the ...

Overnight Trials With Heat Stress in Autonomic Failure Patients With Supine Hypertension

Primary autonomic failure is a neurodegenerative condition characterized by loss of efferent sympathetic function and severe baroreflex impairment. The clinical hallmark of autonomic failure is disabling orthostatic hypotension, but at least half of patients are also hypertensive while lying down. This supine hypertension can be severe and associated with end-organ ...

Phase N/A

PROgressive Supranuclear Palsy CorTico-Basal Syndrome Multiple System Atrophy Longitudinal Study UK

There are a group of neurodegenerative disorders which are often initially diagnosed to be Parkinson's disease (PD), but which are biologically and clinically distinct, and follow a malignant disease course. The three most common conditions are PSP, CBD and MSA. These conditions have a median survival of approximately 6-7 years ...

Phase N/A

Biomarkers in Neural Disorders

Parkinson's disease (PD), a devastating age-related disease that is clinically defined by its effects on the motor system, afflicts more than six million people worldwide, imposing enormous burdens on patients, relatives, caretakers, and society in general. Diagnostic errors are common, particularly as symptoms first arise. The most common misdiagnoses are ...

Phase N/A

Oligomeric Alpha-synuclein in Multiple System Atrophy

Multiple system atrophy (MSA) is a rare neurodegenerative disorder which is characterized by a variable combination of parkinsonism, cerebellar dysfunction, autonomic failure, and additional signs. No effective treatment is available. Together with PD and Lewy body dementia, MSA belongs to a group of neurodegenerative disorders, the alpha-synucleinopathies, which are characterized ...

Phase N/A

Gait Analysis in Neurological Disease

This study aims to determine whether the gait patterns in these subjects differ in predictable and quantifiable ways from those of age- and sex-matched healthy controls. This will be conducted by asking 40 Parkinsonian disorder subjects and 40 age-matched healthy control subjects to walk 9 trials over an 18 ft ...
