"No clarity and Bad care"

My father had a seizure at home, the doctor at A&E told him he had probably experienced a mini stroke and since he looked ok he might as well go home. Shocking. In addition to that his speech was still slurred, after complaints were made he was admitted to a ward in wexham park.

The guidance here clearly states that a scan should be scheduled and that due attention should be paid to difficulties with speech. Frankly appalling treatment considering he has been admitted 3 times in the last month to hospital due an ongoing serious infection. No clarity from doctors about treatment options, mainly it looks like buck passing. What could be improved? The organisation taking responsibility.
