Conversation: The conversation between human and AI assistant.
[|Human|] After an episode of loosing my memory early Monday morning after getting ready for work, I spent three days in Hospital and under went various tests - the last one was Lumbar Punch. The nurse told my wife that there was no fluid extracted. My sick note reads "Tranistent Ischaemic episode",What is this and why no fluid?Thanks
[|AI|]  TIA are mostly caused by embolic episodes where some plaque or clot in carotids or heart sends some embolic which block your cerebral circulation leading to transient stroke. As the circulation get restored you regain strength and consciousness. You need to get ECHO, Doppler of neck vessels, MRI brain, MRI Anglo brain to find the cause. In your case there is no reason use CSF was not aspirated. Probably a second attempt by senior doctor is required.
