Approximately one in 100 patients hospitalised with COVID-19 develop complications of the central nervous system, according to a new study which urges quicker brain imaging for patients. Strokes and brain haemorrhages are among the potentially fatal complications linked to COVID-19 by what has been described as the largest multi-institutional international study of its kind to date.
Neurons communicate with each other via electrical signals and chemical neurotransmitters. At the junction between two neurons (synapse), an action potential causes neuron A to release a chemical neurotransmitter that passes the information to the next neuron. This type of neuron-to-neuron communication is known as evoked neurotransmission.
