Safety would be the primary concern of course when people with hemiparesis live alone or are alone for extended amounts of time. Of course your first references are your doctor, physical therapist and occupational therapists especially. This being stated, I can offer insights on some important items to consider in practical aspects of living alone after a traumatic brain injury or a stroke that result in a severe muscle weakness along the left or right side of the body and is sometimes exhibited in slight nerve damage as with me. Perhaps instead of living by them selves, it would be better to consider us living independently. At this writing, I will have reached almost thirty years of living with hemiparesis. Most of this time I was living alone and working as an engineer and writer, author.
For us, the detrimental effects of hemiparesis are still prevalent even after initial rehabilitation and limited recovery. The effects can change with extreme variation.
