The disorders I selected were Sandhoff Disease and Niemann-Pick Disease. Sandhoff Disease onset is usually at the age of six months according to American Academy of Neurology (2014). It is a severe form of Tay-Sachs disorder that causes a deficiency of enzyme betahexosamindase that accumulates certain lipids in the brain including additional organs. Progressive deterioration of the nervous system, weak motor skills, appearance of a doll-like face, earlier loss of sight, along with involuntary

Abstract— Neurodegenerative diseases causes a wide variety of mental symptoms whose evolution is not directly related to the analysis made by radiologists on basis of images, who can hardly quantify systematic differences. This paper presents a new automatic (Based on software program) image analysis method that reveals different brain patterns associated to the presence of neurodegenerative diseases, finding systematic differences and therefore grading objectively any neurological disorder. An

they study and work on, the brain. Other types of doctors often have patients take MRIs or CAT scans to examine what it is they are looking at. This led Amen to utilize a special type of brain imaging called SPECT. SPECT stands for single photon emission computed tomography. This type of scan measures the amount of blood flow in different regions of the brain. By giving patients these scans Amen is able to gain better insight on what might be causing their mental disorders. He can see if different regions

Diagnosis of Parkinson’s disease is not a simplistic process. Currently, there is not a precise way of diagnosing Parkinson’s, rather Parkinson’s diagnostics is based on clinical presentations and ruling out all other possible explanations for the patient’s symptoms. As a result a correct clinical diagnostics for Parkinson’s disease can take anywhere from two months to eighteen years, depending on the clinical presentation. Additionally many patients are misdiagnosed with Parkinson’s, leading to

Through the decades, researchers have tried to solve the mystery of the enigmatic prefrontal cortex. Along with the famous case of Phineas Gage (Harlow,1848), many studies have attempted to answer the burning question of either or not lesions to the prefrontal cortex lead to an antisocial behavior. The PFC, which is found in the frontal lobe and has an executive function, helps us have an appropriate response to social situations. Why is it important to study this matter? Because we are social creatures

Assessment of PET and SPECT Scanning Systems Introduction The study of positron emission tomography (PET) and single photon emission computed tomography (SPECT) scanning effectiveness in supporting better public health outcomes has been proven with the accuracy these devices provide in diagnosing illnesses and potentially sever medial conditions. The costs of a PET scanning system can easily surpass $1M in system costs alone however (Wagner, 1988). SPECT systems are equally expensive which make

In 2009, he was still a cheerful person with a big smile on his face. In 2010, he could no longer put up that smiley face, but he could still walk with his feet. In 2011, he was not able to walk without the walking aid, but he could still open his mouth to eat. Later in that year, he was already incapable of feeding himself because the food would have been flung away before he could put it into his month, due to the ‘tremor’ in his hand. In 2012, my friend’s grandpa died. He was diagnosed with Parkinson’s

For the pass this assignment will describe the investigations that are carried out to enable the diagnosis of these physiological disorders. For the merit this assignment will assess possible difficulties involved in the diagnosis from their signs and symptoms. P3 There are a range of tests and diagnostic procedures is needed to diagnose dementia, but there are several that are fairly commonly used to diagnose dementia. A GP might refer a person to a specialist to help with the diagnosis. For

the circulation include total T3 and T4 hormone [4], and for the radiological exam, we use various modalities (ultrasound, CT, MRI and Nuclear Medicines). Ultrasound is the leading imaging technique for diagnosis of thyroid diseases [5][6], Computed tomography and magnetic resonance imaging also have a high important role for assessment the thyroid malignancy [7]. Nuclear medicine is the imaging of utilization of radioactive compounds in medicine to image and treat various human diseases. It depends

Intelligence refers to the ability to obtain information and apply skills and consists of different functions, memory, reasoning, logic; these are all controlled by different areas of the brain. Alzheimer’s Disease inhibits short term memory first, before it continually moves throughout the brain, eventually affecting part of the brain that controls involuntary functions. With this in mind someone with MCI would not be able to make clear judgments and recall memory stored in long term memory. The
