Parkinson's disease (PD) is a common progressive neurodegenerative disorder characterized by resting tremor, bradykinesia, restricted mobility, and postural instability. Early diagnosis of PD would be paramount for further treatment and prognosis. The most common neurodegenerative parkinsonian
The increasing prevalence of dementia is a serious threat to our medical system and our society. About 500,000 Canadians are affected with dementia, and this number will rise to more than 1 million in the next 20 years. Dementia already costs our economy 15 billion dollars per year. While much of
Parkinson's disease (PD) is the second most common neurodegenerative disease after Alzheimer's dementia and was originally described as a motor disease. The diagnosis of PD is still based on the core motor features of bradykinesia, resting tremor, and rigidity, primarily as a result of degeneration
Inclusion criteria:
1. PD patients aged 50-79 years diagnosed by neurologist (should exclude vascular parkinsonism, secondary parkinsonism( including toxin, drug, heavy metal, CO intoxication), normal pressure hydrocephalus, multiple system atrophy, progressive supranuclear palsy, cortical basal
Neurodegenerative cerebellar ataxias represent a heterogeneous group of disabling disorders in which progressive ataxia of gait, limb dysmetria, oculomotor deficits, dysarthria and kinetic tremor are the prominent clinical manifestations. Both the hereditary and sporadic forms usually present in
Introduction Parkinson disease (PD) is a neurodegenerative disease of the brain, leads to degeneration and causing the motor and non-motor symptoms. PD is characterized by dopaminergic neurotransmitter deficiency. It is a progressive neurological condition that affects more than 10 million people
BACKGROUND Multiple Sclerosis (MS) is the most common chronic neurological disease affecting young adults, with onset usually at the age 20-40 years. The disease is characterized by two main phenotypes: Relapse-Remitting MS (RR-MS) and Primary Progressive MS (PP-MS). RR-MS is the most common type of
Cervical dystonia (CD) is the most common adult onset dystonia. Abnormal sensorimotor integration and maladaptive plasticity have been proposed as possible mechanisms. Currently, there is no definite way to assess and modify this dysfunctional network. Deep brain stimulation (DBS) is one possible
Deep brain stimulation (DBS) has become the standard functional neurosurgery treatment for drug resistant Parkinson's disease (PD) patients. It has also demonstrated its efficacy to treat various movement disorders as well as neurological and psychiatric disorders. The subthalamic nucleus (STN), the
BACKGROUND Parkinson's disease (PD) is a multi-system neurodegenerative disease affecting a subset of vulnerable cells in various brain structures, including brain stem nuclei. Selective degeneration of dopamine (DA) producing neurons in the pars compacta of the substantia nigra (SNc) is a key
Parkinson's disease (PD) is a neurodegenerative disease whose pathogenic mechanism is the degeneration of substantia nigra of the midbrain, causing the degeneration of dopaminergic neurons in the putamen and caudate nucleus of the striatum, and the dopamine content in the synapses decreases and
Idiopathic Parkinson's disease (PD) is a progressive neurodegenerative disorder of unknown etiology, characterized by bradykinesia (slowness of movements) associated with tremor at rest and/or muscle rigidity. PD is typically associated with a significant loss of dopaminergic neurons in the
Background: Idiopathic Parkinson's disease (PD) is a neurodegenerative disorder involving loss of dopaminergic neurons in the substantia nigra and subsequent dysfunction in the striatum. The diagnosis of PD remains a clinical diagnosis based on patient history and physical exam findings. In 2011 the
