Parkinson’s disease (PD) can be defined as a neurodegenerative illness, in which there is a deficit of dopamine in the body. The body suffers from this in many different ways: impaired gait, bradykinesia, rigidity, tremors, diminished expression, kyphotic posture, seborrhoea, and sialorrhea (Baatile et al, 2000). There have been many studies related to the effect of exercise training on patients with Parkinson’s disease. Campbell et al found that exercise allows for dopamine to be synthesized in

Introduction Parkinson's disease may be described as a progressive neurological disorder, it arises from degeneration of neurons in a region of the brain responsible for co-ordinating movement. The neuronal damage results in a shortage of the brain signalling chemical (neurotransmitter) known as dopamine, resulting in the movement impairments which characterize the disease. 71% of Parkinson’s disease cases are due to a sporadic cause, usually influenced by environmental factors. (1) However, Parkinson’s

were to become available to the public. Memantine is a voltage-dependant N-methyl-d-aspartate (NMDA) receptor antagonist with characteristics of moderate binding affinity and fast receptor kinetics. Memantine acts on the glutamatergic signalling system and ionotropic receptors such as NMDA . Memantine is prescribed to those that experience a loss of memory due to neurological

What are the types of brain injuries that occur in high-impact sports? Some of the types of brain injuries are skull fracture, subdural hematoma, epidural hematoma, subarachnoid hemorrhage, intracranial hematoma, cerebral contusion, juvenile head trauma syndrome, second impact syndrome, concussion and sub concussion and post concussive syndrome. At the cellular level, how are neurons and glia believed to be affected by TBIs? They are to be affected because it affects nerve related circuitry by

Parkinson Disease is a degenerative neurological disorder. Parkinson Disease arises from a combination of genetic predisposition and environment factors, such as exposure to pesticides or solvents. This disease is rarely inherited; you usually have to be first-degree relatives you’re at a more increased risk to get the disease. What happens is your dopamine is decreased and this causes you to be slower. This Disease typically occurs around the age 60-70, but about 5-10 percent of cases onset

Diagnoses Rabies virus is usually diagnosed through DFA or the direct fluorescent antibody test, in animals. For starters, this test detects the presence of any antibodies located in the brain tissue. On the other hand, diagnoses in human can be done through a variety of testing. These types of tests include electron microscopy, and immunochemistry. Through the electron microscopy, a saliva sample is viewed and if positive, one can see the presence of bullet-shaped particles. Moreover, only

5. Reaction of microglia to deafferentation. Deafferentation induces an increase in the number, size of cell body, and processes of microglia in the PrV. This reaction is no longer present after recovery of ION function [38]. Although the effects of microglia reaction on synaptic plasticity in the PrV are still unknown, sensory afferents from whiskers do modify microglia function without a critical period. 6. Receptive fields of PrV cells. Receptive field properties of the PrV cells are investigated

Nitsche et al. (2003) sought to build on previous research pointing to the idea that the primary motor cortex plays a direct role in motor learning by way of acquisition and early consolidation learning (Müllbacher et al., 2002; Nudo, Milliken, Jenkins, & Merzenich, 1996; Jacobs & Donoghue, 1991). Specifically, implicit motor learning, where the subject has no awareness of learning taking place, was studied when subjects were given Transcranial Direct Current Stimulation (tDCS) (2003). Transcranial

Physical struggles are just the start for people with MS as they also have to deal with mental challenges like depression, fatigue, or anxiety. Depression is a serious effect of Multiple Sclerosis and happens to almost all people who are diagnosed. Depression can occur because of all the changes that a patient of MS has to go through while living with the disease like feeling weak and not being able to do any normal task (“Emotional Changes”). People with MS basically have to accept a new way of

Fight or flight response I am sure that you are familiar with the fight or flight response? This is a natural response to danger (stress) of us all – humans and animals alike. Imagine the following scenario: A zebra is peacefully grazing in a savanna. A lion is slowly approaching. At the last moment, the zebra spots it and activates the fight or flight response in order to save itself from the predator. It escapes. At the same moment, the lion also activates this response, but for different reasons
