Active clinical trials for "Frontotemporal Lobar Degeneration"

The purpose of this study is to investigate whether cognitive deficits, structural and functional changes can be detected before symptom onset in presymptomatic progranuline mutation carriers. The main objectives of the project are to identify novel cognitive, brain imaging markers and peripheral biomarkers for early diagnosis of FTLD, and to follow disease progression.

This study is being performed to generate data regarding brain vibration /oscillation differences between individuals with dementia and normal controls. The purpose of this study is to compare signal patterns generated from the impact on the scalp from these brain oscillation patterns from individuals with Alzheimer's disease, Frontotemporal Lobar Degeneration, Mild Cognitive Impairment and Age-Matched Normal Controls.

The purpose of this study is to examine the age and the neurodegenerative disease effects on social cognition. Secondary goals are to better understand the relationships between different component of social cognition, executive functioning, and behavior and describing the neuronal substrates associated to the alteration of the social cognition in ageing and dementia.

This study aims to determine factors related to diagnosis delay for patients with young onset dementia (first symptoms before 60 years old) who live in North of France.

Frontotemporal Lobar Degeneration (FTLD) is the neuropathological term for a collection of rare neurodegenerative diseases that correspond to four main overlapping clinical syndromes: frontotemporal dementia (FTD), primary progressive aphasia (PPA), corticobasal degeneration syndrome (CBS) and progressive supranuclear palsy syndrome (PSPS). The goal of this study is to build a FTLD clinical research consortium to support the development of FTLD therapies for new clinical trials. The consortium, referred to as Advancing Research and Treatment for Frontotemporal Lobar Degeneration (ARTFL), will be headquartered at UCSF and will partner with six patient advocacy groups to manage the consortium. Participants will be evaluated at 14 clinical sites throughout North America and a genetics core will genotype all individuals for FTLD associated genes.

Psycho-behavioral disorders assessment is crucial for the diagnosis and follow-up of patients with frontotemporal degeneration (FTD). DAPHNE scientific staff have therefore developed a quantification and follow-up scale specifically dedicated to patients with FTD in current clinical practice. This scale is called DAPHNE to Disinhibition, Apathy, Perseveration, Hyper orality, Negligence and loss of Empathy.

This study will measure the function of a protein called P-glycoprotein (P-gp), which is found at the blood-brain barrier, a membrane that normally prevents toxic material from entering the brain. Impaired P-gp function may allow toxins to enter the brain and cause some people to develop certain brain diseases. Healthy subjects and people with Alzheimer s disease, Parkinson s disease or frontotemporal dementia who are 35 years of age or older and in overall good health may be eligible for this study. Participants undergo the following procedures during three outpatient visits to the NIH Clinical Center: Medical history, psychological evaluation, physical examination and blood and urine tests, including tests for illegal and addictive drugs. PET scan: This test uses small amounts of a radioactive chemical called a tracer that labels active areas of the brain so the activity can be seen with a special camera. Before starting the scan, a catheter (plastic tube) is placed in a vein in the arm to inject the tracer. The subject lies on the scanner bed, with a special mask fitted to the head and attached to the bed to help keep the head still during the scan so the images obtained are clear. A brief initial scan is done to calibrate the scanner. Then, a radioactive tracer called [(15)O]H(2)O is injected into the catheter and the PET camera takes pictures of blood flow to the brain for about 60 seconds. Next, another tracer, [(11)C]dLop, is injected into the catheter and pictures are taken for about 2 hours to determine how much of this tracer is allowed to enter the brain. Magnetic resonance imaging (MRI): This procedure is done within 1 year (before or after) the PET scan. MRI uses a magnetic field and radio waves to produce images of the brain. For this procedure, the patient lies on a table that can slide in and out of the scanner (a tube-like device), wearing earplugs to muffle loud knocking and thumping sounds that occur during the scan.

This study will use positron emission tomography (PET) imaging to measure a receptor in the brain that is involved in inflammation. Certain neurological disorders, possibly including frontotemporal dementia (FTD), are associated with increased inflammation in the brain. This study may help elucidate the relationship between FTD and inflammation. Patients with FTD and healthy volunteers who are 35 years of age or older may be eligible for this study. Candidates are screened with a medical history, physical examination, electrocardiogram, and blood and urine tests. Participants undergo the following procedures: Whole body PET scan: PET uses small amounts of a radioactive chemical called a tracer that labels active areas of the brain so the activity can be seen with a special camera. The tracer used in this study is [11C]PBR28. Before starting the scan, a catheter (plastic tube) is placed in a vein in the arm to inject the tracer. Pictures are taken for 1 hour. This short scan is done to determine if [11C]PBR28 binds to the subject s receptors, since a number of people do not have binding. Subjects who have binding continue with brain PET and MRI scans, described below. Brain PET imaging: Before starting the scan, a catheter is placed in a vein in the arm to inject the tracer,<TAB> and another catheter is placed in an artery in the wrist to obtain blood samples during the scan. The subject lies on the scanner bed. A special mask is fitted to the head and attached to the bed to help keep the person s head still during the scan so the images will be clear. An 8-minute transmission scan is done just before the tracer is injected to provide measures of the brain that are helpful in calculating information from subsequent scans. After the tracer is injected, pictures are taken for about 2.5 hours, while the subject lies still on the scanner bed. Blood and urine tests are done the day of and the day following each PET scan. Magnetic resonance imaging (MRI): An MRI scan is done within 1 year (before or after) of the PET scan. This procedure uses a magnetic field and radio waves to produce images of the brain. The subject lies on a table that is moved into the scanner (a tube-like device), wearing earplugs to muffle the noise of the machine during the scanning process. The test takes about 1 hour....

The aim of this study is to compare personality and social cognition changes, including emotion detection and self-awareness, and neuroanatomical correlates in patients, and how that affects the caregiver-patient relationship.

The objective of the ADDIA clinical Proof-of-Performance study is to validate the performance of ADDIA' blood biomarkers for diagnosis of Alzheimer's disease (AD). ADDIA clinical study is a multi-centre, non-interventional, prospective, proof-of-performance study with only one visit. About 800 well-characterized subjects will be recruited into 3 groups in 2:1:1 ratio, namely patients with Alzheimer's disease (AD), patients with non-AD neurodegenerative disease (NAD) and 200 control subjects (healthy as compared to their age). 400 patients with Alzheimer's disease (AD): 200 patients with mild AD, 200 patients with moderate-to-severe AD, 200 patients with non-Alzheimer's neurodegenerative diseases (NAD), 200 controls (healthy as compared to their age).
