The causes of encephalopathy are both numerous and varied. Some examples of causes of encephalopathy include: infectious (bacteria, viruses, parasites, or prions), anoxic (lack of oxygen to the brain, including traumatic causes), alcoholic (alcohol toxicity), hepatic (for example, liver failure or liver cancer), uremic (renal or kidney failure),
It is often seen 12 to 18 hours in advance of an unsettled weather system. Cirrocumulus clouds look like many small tufts of cotton, rippled sand or even the scales of a fish (hence the term âmackerel skyâ). Middle clouds: Altostratus, altocumulus and nimbostratus clouds are typically found between 6,000 and 20,000 feet above the ground. Altostratus resembles a smooth gray sheet across the sky. Sometimes the sun shines through the layer as a diffuse ball as if you were looking at it through a pane of frosted glass.
Clouds found in the low altitude range are indicated by the prefix âstratoâ or by the suffix âstratus.â Their bases are below 2,000 meters (6500 feet) in altitude, and except in cold weather when they can contain ice and snow, they are composed of water droplets. Three types of low altitude clouds are stratus, stratocumulus and nimbostratus. Stratus clouds are gray clouds that often cover the entire sky.
