i mean no harm in this question, i’m simply curious as my sister suffers from muscular dystrophy and have always been curious why, genetically, she was dealt such a bad card? at what point in pregnancy do genetics determine our fate?

I understand that this is tagged with ‘biology’ but wanted to add a little input as someone who works with people with disabilities and thought this could help with awareness.

In the UK someone is considered to have a Learning disability if they’re IQ is less than 70. That is the criteria. There is also a written/mathematical/cognitive assessment to support this.

While a ‘learning difficulty’ is something that can affect your ability to learn. Specific examples are dyslexia, ADHD.

America call what British people call a learning difficulty, a ‘learning disability’.

British people then use the term learning disability to diagnoses cognitive impairment, I.e. IQ < 70, while America call it an ‘intellectual disability’ or a global intellectual deficiency. Confusing right?

Autism, Down syndrome, are learning disability- associated conditions but are in fact not a learning disability.

Similarly, muscular dystrophy is in itself, not a physical disability, it is a disease, that causes impairments that can effect the physical functioning of a person, for long-term, which makes it a physical disability. Some people can have a brain injury that constitutes a physical disability, others with the same type of injury can have no physical disability!

I hope people find this insightful as I do.. it’s a super common misconception!
