2 Impact of intensive interventions to lower blood pressure on cognitive function, functional ability and quality of life What are the long-term effects of intensive interventions to lower blood pressure on cognitive function, functional ability and quality of life compared with standard 2022 interventions in people with acute intracerebral haemorrhage? [2022] For a short explanation of why the committee made this recommendation for research, see the rationale section on blood pressure control for people with acute intracerebral haemorrhage. Full details of the evidence and the committee's discussion are in evidence review E: intensive interventions to lower blood pressure in people with acute intracerebral haemorrhage. 3 MRI brain scanning Does early MRI brain scanning improve outcomes after suspected transient ischaemic attack (TIA)? [2019] For a short explanation of why the committee made this recommendation for research, see the rationale section on imaging for people who have had a suspected TIA or acute non-disabling stroke. Full details of the evidence and the committee's discussion are in evidence review C: TIA imaging. 4 Avoidance of aspiration pneumonia Does the withdrawal of oral liquids or the use of modified (thickened) oral fluids prevent the development of aspiration pneumonia after an acute stroke? Why this is important People with dysphagia after an acute stroke are at higher risk of aspiration pneumonia. The guideline development group considered how best to reduce the likelihood of people with acute stroke developing aspiration pneumonia, but there was insufficient evidence on which to base a recommendation. Current clinical practice dictates that those people with clinical evidence of aspiration are given 'nil by mouth' or are given modified (thickened) oral fluids. However, there is little evidence to suggest that withdrawal or modification of 2022 fluids reduces the incidence of pneumonia.
