Neurodegenerative Disorders: Alzheimer’s Disease 1. Amyloid Precursor Protein (APP) Alzheimer’s disease (AD) remains a major cause of senile dementia‚ which is characterised by an impairment of neuronal and synaptic function in addition to the accumulation of β-amyloid plaque and formation of neurofibrillary tangles within distinct portions of the brain (De Strooper and Annaert‚ 2000). Progression of this distinct pathology of neurodegeneration does not typically vary from patient to patient

Abstract: Alzheimer disease has become a common disease in aging‚ which accounts for 60 to 80 percent of dementia cases (Qiu‚ Kivipelto & Strauss‚ 2009). β-Amyloid deposition in brain is associated with cognitive decline in aging‚ which is associated with the risk of developing Alzheimer Disease. Low-density lipoprotein (LDL) cholesterol is collected in the walls of blood vessels‚ which can cause blockages and cerebral amyloidosis if the LDL level becomes higher. Since many patients with cerebral

The Infant brain begins to develop a few weeks after conception‚ and most of the definable structures begin to develop at about eight weeks after conception. The first synapses occur seven weeks into the pregnancy within the spinal cord. Synapses occurs when neurons pass signals between each other to relay and receive information. A neuron consists of a cell body‚ multiple dendrites‚ and an axon. The cell body serves as the command center for the neuron‚ it contains DNA (deoxyribonucleic acid) and

ADHD Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurological brain disorder that manifests as a persistent pattern of inattention and/or hyperactivity. ADHD is broken down into three subtypes: predominantly inattentive ADHD‚ predominantly hyperactive-impulsive ADHD‚ and combined type ADHD. ADHD begins in childhood‚ and has only recently been understood‚ can persist into adulthood as well. While some children outgrow ADHD‚ about 50% to 60% continue to have symptoms into adulthood.

the brain‚ implicated in reward‚ motivation‚ and memory. More specifically‚ the ventral tegmental area (VTA) and nucleus accumbens are two regions that directly mediate addiction. The VTA‚ activated by addictive substances‚ is the site of dopaminergic neurons that project onto the nucleus accumbens in the ventral striatum (Adinoff‚ 2004). Therefore‚ studies on addiction usually center around these regions to explore the genetic and neurobiological basis underlying this chronic brain disease. One
