Neuropsychiatric symptoms form part of the clinical picture of Alzheimer's disease (AD) and other dementias. Irrespective of the severity of the disease, the most frequently encountered symptom is apathy. Apathy is increasingly diagnosed in patients with neurological and psychiatric conditions. Apathy is a disorder of motivation, defined as "the direction, intensity and persistence of goal-directed behaviour". Most of the current descriptions acknowledge this point and consider apathy in terms of a lack of goal-directed behaviour, cognition or emotion. The classical neuropsychiatric symptom assessments are subjective structured interview-based, using input from the caregiver and/or the patient. New technologies are likely to provide us with a more objective measure. An example is ambulatory actigraphy, consisting of a piezoelectric accelerometer designed to record arm movement in three dimensions.
The aim of the present study is to assess using actigraphy and video recording signal, AD patients with (n = 15) and without (n = 15) apathy and control subjects (n = 5) during an activity of daily living scenario .

The LifeZig Project is a research study of a new reminiscence activity for individuals with Alzheimer's Disease (AD) and other types of dementia, based on the LifeZig system, with personal...
The primary purpose of this study is to explore the underlying mechanisms that link sleep to Alzheimer's disease (AD), with special focus on the clearance of metabolites in the extracellul...
The purpose of this study is to use a new method to differentiate mnesic abilities of early alzheimer patients and patients with a depressive disorder. This method is based on the recordi...
The purpose of the study is to verify the ability of the HyperQ signal to detect Dobutamine induced Ischemia. The gold standard for ischemia will be the results of Angiography if performed...
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study of lemborexant (4 dose levels) or placebo taken daily for 4 weeks in approximately 125 male or fem...
Sleep disturbances in patients with Alzheimer's disease have not been systematically evaluated, because sleep monitoring has proved difficult. Our goal was to quantitatively characterize sleep disturb...
Home Video Telemetry (HVT) combines ambulatory EEG with simultaneous video recording. No previous reports have compared HVT and inpatient video telemetry (IVT) in a purely paediatric population. This ...
Clinical evaluation is of utmost importance in the semeiological description of motor disorders which often require video recording to highlight subtle signs and their subsequent evolution. After revi...
Intraoperative recording devices are being increasingly used to provide video for contemporary surgical training. The objective of this study was to evaluate the use of a smartphone as a low-cost alte...
The level of the presynaptic protein growth-associated protein 43 (GAP-43) in cerebrospinal fluid (CSF) has previously been shown to be increased in Alzheimer's disease (AD) and thus may serve as an o...

Abnormal structures located chiefly in distal dendrites and, along with NEUROFIBRILLARY TANGLES and SENILE PLAQUES, constitute the three morphological hallmarks of ALZHEIMER DISEASE. Neuropil threads are made up of straight and paired helical filaments which consist of abnormally phosphorylated microtubule-associated tau proteins. It has been suggested that the threads have a major role in the cognitive impairment seen in Alzheimer disease.

Psychiatry is the study of mental disorders and their diagnosis, management and prevention. Conditions include schizophrenia, severe depression and panic disorders among others. There are pharmaceutical treatments as well as other therapies to help...
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
