Herpes zoster ophthalmicus Herpes zoster ophthalmicus Herpes zoster ophthalmicus (HZO) and also known as ophthalmic zoster is a disease characterised by reactivation of dormant varicella zoster virus residing within the ophthalmic nerve (the first division of the trigeminal nerve). This condition is an important subtype of shingles, representing 15% of all cases. Herpes zoster ophthalmicus is transmitted via direct contact or droplets. Varicella zoster virus is a DNA virus which produces acidophilic intranuclear inclusion bodies. The virus is neurotrophic in nature. The frontal nerve is more commonly affected than the nasociliary nerve or lacrimal nerve. Anterior uveitis develops in 40–50% of cases with
Short-term memory becomes even more difficult. However, capacity of STM can be affected by the following: Influence of long-term memory, Reading aloud, Pronunciation time and Individual differences. Diseases that cause neurodegeneration, such as Alzheimer's disease, can also be a factor in a person's short-term and eventually long-term memory. Damage to certain sections of the brain due to this disease causes a shrinkage in the cerebral cortex which disables the ability to think and recall memories. Memory loss is a natural process in aging. One study investigated whether or not there were deficits in short-term memory in older adults. This was a previous
