Three researcher identified 3,105 peer reviewed articles through database search. We narrowed and assessed 15 articles out of those 3,105 to address the research questions presented in this systematic review. The primary exclusion criteria articles published after 1990. Table 1 summarizes the study characteristics. Anderson, Damasio, Kilma, Bellugi & Brandt (1991) observed three patients with aphasia who were taught how to fingerspell. Out of all of the patients, two patients were able to…

Did you know that possessing a greater amount of dopamine receptors in the hippocampus results in better episodic memory? It’s a wonder why some people have great memory of past events, while others have none. As an adult it gets increasingly harder to remember events you experienced as a child. It has always been a phenomenon as to why you can’t remember the memories you had as a child. Why you forget what happens before the age of four. As an infant your brain is busy making new cells in the…

In medicine, an early diagnosis can mean the difference between life and death. Advancement’s in technology are making an early diagnosis for many diseases possible. One of these diseases is Alzheimer’s disease. According to the Alzheimer’s Foundation of America, (AFA, 2015) “Worldwide it is estimated that 24 million people have dementia, the majority of these people are also thought to have Alzheimer’s disease.” The AFA (2015) also states that, “Alzheimer’s Disease affects 5.1 million…

I Blame the Hormones By: Taylor Aubin Organs and tissues that make up the endocrine system are the hypothalamus, pituitary gland, thyroid gland, thymus, suprarenal glands, pineal gland, parathyroid glands, heart, kidneys, adipose tissue, digestive tract, pancreas, and gonads. The effects of the endocrine system are vast and impact almost every organ and cell of the body. This system produces hormones that help maintain homeostasis through the regulation of metabolism, growth, tissue function,…

General Causes Cerebral palsy occurs from brain injuries or serious brain malformation which occur during early development. Every case of this disorder is unique. Cerebral palsy is different from traumatic brain injuries or TBI’s because they occur before the brain has fully developed. Cerebral palsy is not a hereditary condition. Weather Cerebral palsy is congenital or not depends on the timing of the brain injury. According to the Center for Disease Control, “The majority of CP (85%–90%) is…

The lateralization of brain function refers to how some functions, or cognitive processes tend be more dominant in one hemisphere than the other (Sperry, 1968). The medial longitudinal fissure splits the human brain into two distinct cerebral hemispheres, joined by the corpus callosum (Gray, 1985). The two hemispheres demonstrate strong, but not comprehensive, bilateral symmetry in both structure and performance. Handedness is not a single variable, but can be placed in a spectrum of 4 separate…

Deep brain stimulation is a technique where an electrode is placed within certain areas of the brain. Electrical impulses are then created by the electrode to regulate abnormal impulses. Under the patient’s skin near the collarbone, the electrode is connected to a stimulator or pacemaker (Pluta, 2011). Deep brain stimulation requires locating the target part of the brain and then drilling a small hole in the skull to allow the placement of an electrode. During the implantation of the…

Congenital hemiplegia is a type of cerebral palsy that is caused by brain damage that occurred either before or during birth. It can also be caused by brain damage, sometimes stroke, during childhood (gosh.nhs.uk). With hemiplegia only one side of the brain is affected therefore causing paralysis in the opposite side of the body. The Children’s Hemiplegia and Stroke Association, CHASA.org, is a very useful site that not only has information specific to the treatment and effects of the…

As we can see the temporal lobe is a involved in many vital functions of the brain, thus its damage can cause visual and verbal impairments or, in more severe cases memory disturbances. Due to the fact that it involves the auditory cortex, the epileptic patiens are often extremely sensitive to different voices and noises, they get tense from the various forms of rowdiness. As we have already seen, seizures can be caused by different factors, but there are several common triggers, such as:…

The frontal lobe is the largest lobe in the brain and is situated at the front of the skull. “The frontal lobes are involved in motor function, problem solving, spontaneity, memory, language, initiation, judgement, impulse control, and social and sexual behavior” (CNS, 2015). The frontal lobe is important for many different things, and if damage occurs it could cause a significant impact on any one of these or multiple areas. With a traumatic brain injury the communication intent, transmission,…
