In a paragraph briefly discuss the pathophysiology of the medical diagnosis- viral conjunctivitis
Viral conjunctivitis, also known as pink eye is a viral infection which causes reddening and irritation of the eye which is highly contagious. The surface of the eye is formed by the conjunctival and corneal epithelium and the tear film. Various microorganisms can come into contact with the tear film and result in infections. The reason for the virus’s attack is a result of reduced immunity and external contamination of the eye. The eye is prone to blood-borne infection and invasion from adjacent sides of the eye. A viral infection activates a leukocyte, and they replicate in the conjunctival mucosal cells. Inflammation of the lymphocytes causes attraction of red and white blood cells to the infected area. (Scott, 2016). This causes the reddening of the eye. The white blood cells reach the conjunctival surface and build up there as they can pass through the dilated and increasingly permeable capillaries. (BMJ, 2016).
In a paragraph briefly discuss the pathophysiology of the medical diagnosis- ADHD
There is no clear pathophysiology of ADHD. However specific brain areas are affected by the disease, which is treated by regular use of Psychostimulants. The main areas of the brain, the frontal and prefrontal lobe are involved. However, the parietal lobe and the cerebellum might be involved too. These areas are affected due to a deficiency in neural transmission. As these areas are produce and work with neurotransmitters like dopamine and norepinephrine, the condition can be improved by regular dosage of these in the body. ADHD is also associated with alterations in the frontostriatal areas, which was discovered when children with ADHD were compared with normal children. Moreover neurochemical changes in the brain also result in ADHD in adolescents. Also, individuals with ADHD have inhibition impairment which is a condition in which they cannot stop their responses. (Soreff, 2015).
