Research has determined that ageing is important to consider when looking at neurodegenerative diseases and there cause‚ such as Alzheimer’s disease. It is thought that neuronal loss is primarily involved in neurodegeneration when in fact it seems that synaptic strength‚ or plasticity‚ is more vulnerable to the process of ageing (1). Biochemical and structural alterations of the synapse such as changes in lipid composition in certain areas of the brain are also thought to be associated with this

Intensive Care Nursery House Staff Manual Inborn Errors of Metabolism INTRODUCTION and PATHOPHYSIOLOGY: Inborn Errors of Metabolism (IEM) comprise a group of disorders in which a single gene defect causes a clinically significant block in a metabolic pathway resulting either in accumulation of substrate behind the block or deficiency of the product. All IEMs are all genetically transmitted typically in an autosomal recessive or X-linked recessive fashion. The major categories are: Organic

Complex internal dynamics between place and grid cells Spatial learning and memory have been implicated in navigation and the formation of episodic memory (Pilly & Grossenberg‚ 2011). Episodic memory can be affected by neurological disorders‚ such as dementia and Alzheimer’s disease. A better understanding of the neural mechanisms underlying spatial behaviour could therefore help to understand such cognitive decline. An important contribution to this endeavour was the discovery of spatially modulated

Secondary excitotoxicity is thought to be more relevant to chronic neurodegenerative disorders than the classical acute form. In this pathway increased glutamate levels are not required as disturbances with the neuronal resting membrane potential cause glutamate receptors to be over-activated by physiological levels of glutamate. In a neuron which is affected by another pathological process and shows reduced ATP production‚ Na+ dysfunction or impaired glucose metabolism and as a result has an abnormal

Dementia awaress essay 1.The word dementia describes a set of symptoms that may include memory loss and difficulties with thinking‚ problem-solving or language. Dementia is caused when the brain is damaged by diseases‚ such as Alzheimer’s disease or a series of strokes.The term ‘dementia’ is often misunderstood and some people use the terms ‘senile’‚ ‘dementia’ and ‘Alzheimer’s’ interchangeably‚ thinking that they are one and the same thing. 2.Key functions of the brain that are affected by

 chronic constipation is infrequent bowel movements or difficult passage of stools that persists for numerous weeks or longer. Constipation is normally defined as having fewer than 3 bowel movements a week. although occasional constipation may be very commonplace‚ a few human beings revel in continual constipation that could intervene with their potential to move about their daily responsibilities. chronic constipation may also cause excessive straining to have a bowel motion and different signs
