Hello, I am looking for someone to write an essay on Neuro Final Project. It needs to be at least 2000 words.

Early symptoms include an influenza-like illness with patients experiencing high body temperature and this is followed by a long period without symptoms. HIV causes AIDS and as the illness progresses it interferes with the immune system by attacking the CD4 T-cells leaving the body vulnerable to opportunistic infections and tumors. The presence of symptomatic cognitive disability foretells non-central nervous system morbidity and overall HIV mortality. Dementia may be caused by rapid evolution of HIV in certain brain regions causing a cycle of infections of macrophages and inflammation. HIV moves around the brain in distinct paths and evolves at different rates depending on where it is on the brain due to the different genetic sequences in the virus particles in the different areas of the brain. Patients in high risk environments are at a greater risk of cognitive complications related to immunosuppression. AIDS Dementia complex (ADC) is a type of dementia that occurs in advanced stages of AIDS and leads to the loss of noetic abilities such as memory, abstract thinking and judgment. It affects brain function in areas of thinking ability, behavior, mood, coordination and movement. Brain monitoring or neuroimaging involves the use of various techniques which can be either invasive or non-invasive to view the structure and function of the brain. The non-invasive techniques include PET, fMRI, SPECT, MEG among others. The Functional magnetic resonance imaging (fMRI) involves the use of magnetic properties of oxygenated and deoxygenated hemoglobin to observe the changing blood flow in the brain due to activity of the nervous system. The patient is presented with various touch, visual and sound stimuli and the scanners are used to show brain structures and processes associated with thought, perception and action. Positron emission tomography (PEF) involves measuring active chemical compounds emission from radioactively labeled metabolically active chemicals injected to the bloodstream of a patient. The labeled compound makes its way to the brain through the bloodstream and sensors detect the radioactivity as the compound accumulates in the different regions of the brain. The compounds show blood flow and the metabolism of oxygen and glucose in the tissues of the brain which reflects the amount of brain activity in those regions. It helps in the diagnosis of brain disease like brain tumors, stroke, and neuron-damaging diseases such as dementia (Alzheimer’s disease and Pick’s disease) all of which cause significant brain metabolism, which is easily detectable on PET scanners. Single-photon emission computed tomography (SPECT) uses radioisotopes that emit gamma rays and a manna camera to record data that a computer uses to construct images of the active regions of the brain. The subject is injected with a radioactive tracer which is rapidly taken up to the brain but does not redistribute. It shows the cerebral blood flow at the time of the injection and is especially useful for epilepsy imaging.
