decline in language may be a predictor of Alzheimer’s. Alzheimer’s is characterized as a change to baseline cognitive processes, not necessarily a decline in memory or language, as these declines are normal with healthy aging. While performing fine motor tasks such as writing, drawing or dressing, certain movement coordination and planning difficulties may be present, but they are commonly unnoticed. During the final stages, the patient is completely dependent upon caregivers. Several…

will trigger feelings of anxiety, depression, lack of motivation and decreased ability to concentrate. This “crash” does not typically last long. However, chronic users of MDMA will experience longer crashes due to decreased serotonin-containing neurons and damaged serotonergic axons in the…

Zebrafish is an excellent candidate as a model organism for studying early developmental process. When comparing the results of ethanol it is evident to see the correlation of higher concentration of ethanol exposure would equal to greater defects in the early development of Zebrafish embryos. For the experiment with just alcohol treated ethanol I believe that after 48 hours I will see embryos not be dead, but lack of movement. This will untimely lead to a shorter life if they reach to maturity…

OVERVIEW: Huntington's disease (HD) is an inherited disorder that causes degeneration of brain cells, called neurons, in motor control regions of the brain, as well as other areas (NINDS, 2016). Huntington’s disease is caused by a mutation in the gene for a protein called huntingtin. The defect causes the cytosine, adenine, and guanine (CAG) building blocks of DNA to repeat many more times than is normal (NINDS, 2016). Huntington’s disease is a progressive brain disorder that causes…

Overview Background Transient global amnesia (TGA) has been a well-described phenomenon for more than 40 years. Clinically, it manifests with a paroxysmal, transient loss of memory function. Immediate recall ability is preserved, as is remote memory; however, patients experience striking loss of memory for recent events and an impaired ability to retain new information. In some cases, the degree of retrograde memory loss is mild. Many patients are anxious or agitated and may repeatedly ask…

Alzheimer's is a genetic disorder that can be inherited. Most people develop this disease when their 65 years or older. Alzheimer's is memory loss. The symptoms of this disease are Forgetfulness,loss of concentration, and language problems etc. Alzheimer's is a change in a gene that increases a person's risk of developing a disease. Which is a genetic mutation. This gene can be passed on to little kids so they can grow up and later have Alzheimer's. Alzheimer is not only reason or cause of…

Individuals with this disease show two different types of abnormal lesions that aren’t seen in normal brains. The beta-amyloid plaques, which are lumps of protein and other cellular material that form in and around the neurons, and neurofibrillary tangles, which are insoluble fibers made up mostly of the protein tau that build up inside nerve cells, both of these lesions will clog the brain; however physicians and scientists are unsure whether these lesions actually cause…

The neurodegenerative diseases, or dementias, are characterized by progressive and irreversible degeneration of the neurons from specific regions of the brain. The pattern of neuronal loss is selective and compromises one or more groups of neurons, without affecting the others. An interesting aspect of these dementias is them arise without any apparent triggering stimulus and in patients with no history of neurological deficits. Alzheimer’s disease is the most prominent of these dementias,…

Huntington’s disease is a progressive and fatal type of dementia caused by dominant allele in chromosome 4. (Kail & Cavanaugh, 2016, 2013, 2010, p. 44) It is an autosomal-assertive, progressive neurodegenerative affliction with a definite phenotype, including chorea, lack of coordination, cognitive deterioration, and behavioral difficulties. (Perandones, Micheli, & Radrizzani, 2010, p. vii) Huntington’s disease was identified by George Huntington in 1872. Huntington Disease is also referred to…

Aphasia is a communication disorder that could result from any form of damage to the parts of the brain that involve the use or interpretation of language. This disorder is more common in older adults and moreover anyone that has had a stroke at some point in their life is likely to have some form of aphasia because of that stroke. In short aphasia gets in the way of a persons ability to use or understand words, however aphasia does not impair an individuals intelligence. Aphasia only affects a…
