My mum had a haemorrhagic stroke, like yours, at 50. It was completely out of the blue. Medics also said it must have been due to a freak rise in BP but no one really knows why this happened. She was in hospital for 3 months.
That was 8 years ago now. When she first had the stroke she could barely speak, struggled swallowing and was completely paralysed down her right side. She couldn't walk and even had difficulty rolling over. she slept for most of the time and could do nothing independently. Her coordination was gone so she needed help eating etc.
Today, she still has aphasia but it is vastly improved and only really noticeable when she is tired. She still gets very, very fatigued and needs lots of rest. She had to retire, there is no way she can work like she used to, but she did volunteer on a telephone advice service for a while for 8 hours a week. She can now walk with a stick for short distances. She has some movement down her right side but a lot of spasticity, which makes that side painful. She can make herself a cup of tea and some toast, shower and toilet independently but needs help getting dressed. She can’t really do any household tasks so needs a carer (my dad).
Recovery from a stroke is so variable, everybody has individual recovery journeys and so I can only share my experience. It is a long process of recovery and you have to fight for the support, in my experience. We thought my mum might die so we are so relieved to have her. Life has completely changed for her and for us, however, we’ve learnt to adapt. Mum has a full life with friends and family, she goes on holiday, goes out with friend etc etc. there is still joy. She has made peace with adapting to her new normal, but it wasn’t easy to get there.
Advice - once the NHS discharges you it can feel scary, seek support from stroke charities, national and local. They offer great advice in resources and peer support for both you and your mum.
Get occupational health involved to help you fit the house to better enable your mum.
Look out for her mental health, it is a massive and traumatic life change. My mum really struggled once through the immediate crisis.
Think about the future; plan.
Get support yourself. My MH took a hit, it was a sad uncertain time. I was in my 20s but it is so at anytime.
Good luck, things do get better. Take each day as it comes, get support for yourself. PM me if you like.
