Aging is defined as the accumulation of changes that can be biological, psychological or social, and is among the greatest known risk factors for most human diseases1. While aging has always been seen as a natural process, some scientists are starting to study it as an illness that needs to be cured2. Although these studies aim to such big goals, present knowledge about this process is still really poor. In aging brain, there are roughly two categories for the type of changes suffered:…

So what is music therapy? According to the American Music Therapy Association, music therapy is “the clinical and evidence-based use of music interventions to accomplish individualized goals”. Simply put, music therapy is the use of music to improve overall health. It was first developed in 1944 at the University of Michigan. It has been used to treat people with depression, anxiety or post traumatic stress. In recent years, music therapy has been used to treat ADHD in children. According to…

“A new study has found that about 92 percent of high school students aren 't getting enough sleep. According to the National Sleep Foundation, teens need at least nine hours of sleep per night” (Tweed, 2010). Getting a good night 's rest can make a big difference in how a person feels. Sleep too often is treated like an option when it very well is not. Sleep is essential for survival and plays an important factor in being healthy. School should start later in the morning due to teens suffering…

the outside layer of the brain and the basal ganglia is responsible for executing movement. When cells of these brain regions are damaged abnormal behavior occurs such as Huntington disease. Another key aspect of this model is the activity of neurotransmitters. They act as messengers and if they have low activity then hormones fail to get released causing abnormal behavior to emerge. The Behavioral Model involves internal and external forces altered by the environment. This model…

In “Can Science Stop Crime”, David Pogue the presenter is going to show how science could possible stop crime. In the introduction of the program Pogue has the question is whether violent brains are created by nature or nurture. The first example giving was an ex-gang member/ mixed martial art teacher Eugene. Eugene teaches kids and teenagers to take their anger out on the ring. His son Nikko was a troublemaker as a kid and had joined a Taliban gang where he was bad and violent. Eugene now…

to one cause but may be from numerous factors such as biological causes, family history, psychological issues, and traumatic life events. Biological factors can cause anxiety problems because it can occur interference with the regulation of neurotransmitters and the chemicals in the brain that transmit signals between cells. Psychological factors that can contribute to the etiology of anxiety usually are broken down into the cognitive, behavioral, and psychodynamic. Cognitive emphasizes on…

Schizophrenia usually begins between the ages of 16 and 30; however men are often affected earlier than women. People who develop schizophrenia portray a wide-ranging breakdown of perception and their thoughts. The beginning symptoms of schizophrenia can present trouble concentrating or sleeping may start becoming avoidant towards friends and family. This is due to how the illness is affecting the person’s brain. As this mental illness begins to progress, the next stage is beginning to speak…

stress increases nerve growth factor gene expression, which increases the growth of sympathetic nervous system neural fibers in the lymph node tissues that structure immune responses. At a later time, when stress is experienced again, more neurotransmitters will be released in the lymph nodes because of the increased number of neural fibers, which is a direct consequence of the social factor stress from the earlier time. The immune system responds more poorly to a viral infection as a result.…

borderline personality disorder. Several medications have used as mood stabilizers are: Carbamazepine (such as Tegretol or Epitol), Divalproex (Depakote), and Lithium (such as Lithobid). These medicines help stabilize certain brain chemicals called neurotransmitters, which control emotions and behavior. Balancing these brain chemicals may help you avoid impulsive and reckless…

processes; this includes using past experiences to govern these behaviors. The affect childhood trauma has on these processes can be seen in how problems are solved even into adulthood. Unresolved stress in childhood reduces the amount of inhibitory neurotransmitters (GABA), and the production of opioids, which give us our “good feelings”. As a result, specific genes can be “turned on or off” and brain stress response systems can be wired permanently for oversensitivity and overreactivity…
