Feeling unsettled, having the constant need to change positions and move around might indicate sensory changes related to brain injury. Following a stroke, people can recover and change in the way they respond to the environment around them. Some people can become more agitated, wanting to move around more and excessively seek sensory experiences around them. Other people can become more labile or apathetic. You might find it helpful to speak to your GP, who can assess your dad and discuss your options for accessing help. Health professionals such as occupational therapy, neuropsychologists and clinical psychologists can work with you and your dad to help develop a daily routine to support better sleep patterns and meaningful activities that support recovery of sensory awareness. Behavioural management strategies provided by health professionals may also help carers to provide the right kind of support for stroke survivors to feel more settled. If you would like more specific advice, I encourage you to reach out to the health professionals on StrokeLine who will be able to discuss the difficulties your dad is having and discuss options for accessing support.
