There are many causes of dementia and according to Janssen Pharmaceutica N.V., “There are some causes of dementia that are treatable which are head injuries, brain tumors, infections (such as meningitis, HIV/AIDS, or syphilis), simple and normal pressure hydrocephalus (i.e. when the fluid in which the brain floats is collecting outside or in the cavities of the brain, compressing it from outside), hormone disorders (i.e. that is, disorders of hormone-secreting and hormone-regulating organs such…

Part 3: Alzheimer’s Disease: A Doctors Secret Have you ever thought about how you will die, or what diseases you will get diagnosed with in you older age? Alzheimer’s disease is a “forgotten" thing in the younger generations, but its more present than we think. Many people 65 years and older have the disease without even knowing it until incidents like backing up out of the garage with the door still down, or falling asleep at the wheel, happen and they become utterly confused. So, is it…

An average person can remember things that happen in their lives whether it be for a short time, or a long time. There are many factors involving the memory of the brain such as sleep. The human brain is a unique and amazing place where one can store things about their life. Some would say, that the human memory is like a huge library of moments stored throughout our brains. In my opinion, this is a great process is that if we are experiencing something new in our life, we can go and look up a…

The choices I make now as a teenager and not nearly as important as those I will make as an adult. WRONG !!! The choices you make as a teenager greatly influence your ability to choose in your future. Your first choice is to decide which element in your brain will make that choice, emotion or your Intellect. Apparently for teenagers this is not an easy thing to do because, guess what, – our Brains are still developing – we do not yet have the brain capacity to easily make a reasoned choice.…

filled with undiscovered mysterious. The brain is composed of several different parts, each with its own job to carry out through the use of nerve cells. These nerve cells, or neurons, are abundant in the brain, creating over a thousand trillion connections among the hundred billion cells found within the brain. The neurons receive, process and transmit information from all parts of the body, controlling various aspects of the…

Multiple Sclerosis (MS) is a disease or autoimmune disorder which affects the central nervous system of an individual; the brain and spinal cord. Though not much is known of the cause of MS, researchers believe that Multiple Sclerosis causes the body’s immune system to attack the myelin sheath. The myelin sheaths are an insulating coating around the nerve cells, consisting of a mixture of proteins and phospholipids, which help to increase the speed at which nerve impulses are conducted. As the…

This would mean that our memory and other cognitive functions would get irreversibly worse once we reached the legal drinking age. Thankfully, in the last few years, science has discovered that the human brain is more than capable of making new neurons well into old age. No matter how old you are, you’re never too old to rewire your brain…

patients (Dutta 2007). In MS, the oligodendrocytes and myelin sheaths of the central nervous system (CNS) deteriorate and are replaced by hardened scar tissue. To understand how MS affects the nervous system, we must understand how neurons transmit messages. Neurons transmit messages through the nervous system across a small gap called the synapse. At the synapse, electrical impulses are converted into chemical impulses in order to cross the synapse. A normal functioning nervous system includes…

stimuli and necessary functions at up to two hundred and eighty miles per hour. Nerves are made up of neurons are classified based on function: sensory, motor, and interneurons. Sensory neurons send messages based on their specific sense to the brain. Motor neurons control the contraction and extension of muscles, and interneurons are neurons that communicate with and relay messages between neurons. The central nervous is made up the brain, which is made up the cerebrum, the cerebellum, and the…
