Dementia

MS occurs when the immune system attacks the myelin sheath that cover and protect the nerve fibers. When myelin is damaged the information, or the nerve impulses, from the sensory nerves can no longer reach CNS , which consequently lead to wrong responses in the body. Because MS is unpredictable disease, the progression of MS differ from one patient to another. Therefore, doctors have to follow the patient’s case carefully to recognize whether the Disease progresses to later stages or not. The…

Spinal muscular atrophy (SMA) is inherited disorder that affects the lower motor neuron in the anterior horn cells of the spinal cord and brain stem resulting in progressive weakness of the skeletal muscles [1]. It is considered as one of the most common autosomal recessive diseases and leading genetic cause of death during childhood [2]. The primary cause of SMA is mutation of the spinal motor neuron 1 (SMA1) while the severity of the disease is determined by the number of identical spinal…

Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease that involves motor neurons in the brain and spinal cord. ALS is considered to be one of the most common progressive neurological diseases, affecting approximately 20,000 individuals in the United States in a given year (Fried-Oken et al., 2006). Etiology of ALS remains unknown; however, there appears to be an existing genetic component associated with this disease. Changes in speech are first seen in patients with bulbar onset…

Nerve cell degeneration that occurs in AD (as shown in Figs. 4 & 5) reflects in a great way symptoms that the individual experiences. Typically, nerves degeneration occurs first in the brain area responsible for learning and memory, and gradually spreads to cells controlling other aspects such as thinking, judgment and behavior. Eventually, damage reaches nerve cells that control and coordinates movement. Figure 4 Brain from normal elderly person (upper left and right)vs. brain of…

There are three stages of alzheimer's, early stage, mild to moderate, and severe alzheimer’s. Learning, memory thinking, and planning is affected in the early stage. Speech and comprehending speech is affected in the moderate stage. In the severe alzheimer’s stage, the individual is unable to recognize family and loved ones, unable to care for themselves, and lose ability to speak. Scientists have been exploring if alzheimer’s can be prevented in health and lifestyle factors like exercising,…

People often take their ability to see for granted. Vision allows a person to appreciate surroundings, makes it easier to perform tasks, and in general, do more, even the dangerous. However, like every other part of the body, the eyes are at risk of impairment resulting in loss of vision. Ageing comes with bodily dysfunctions. Arthritis, hypertension, and memory loss are all examples. So, too, is age-related macular degeneration (AMD) which leads to gradual central vision loss. It might be…

First, you said only one eye has leukocoria in this infant. Leukocoria is a common clinical feature of retinoblastoma, and this indication is usually a late sign of the disease (Balmer et al., 2006). Retinoblastoma can be either a hereditary disease and a nonhereditary disease. Generally, 60% of the cases of retinoblastoma are nonhereditary, with the remaining 40% being hereditary. Usually, 25% of the hereditary cases have family disease history, which is what we have in this case (NORD).…

Psoriasis on scalp (Scalp Psoriasis) is an inflammatory and persistent disease. The main causes of this disease are not yet identified but it is believed that it is slightly hereditary. The common reasons are lack of personal hygiene, repeated use of blow dryers and some fashion products. It takes several years to show up on the scalp. It is mostly seen in adults compared to children. It is seen in both sex but little more in women compared to men. Scalp psoriasis takes place in three phases.…

The Forgetting 1.) Alzheimer’s disease essentially takes away who you are as a person. Alzheimer’s takes away the personality and memory of a person with the disease. The symptoms of Alzheimer’s begin when the synapses are disrupted. Plaque forms between nerve cells and blocks communication. Neurons in the brain cannot connect and synapses disappear. Not only does Alzheimer’s disease affect the synapses in the brain, it also attacks the hippocampus, which is the main component of memory, and new…

Alzheimer's disease usually develops through several steps and stages slowly and progressively gets worse over the years. It eventually affects most parts of your brain, including the memory, thinking, judgment, language, problem-solving, personality and movement[1]. The rate of progression for Alzheimer's disease differs extensively. On average, people with Alzheimer's disease live 8 to 10 years after diagnosis, but some people can survive 25 years[2]. There are Three important stages of…
