ご質問ありがとうございます。
「脳損傷により意識障害、麻痺や嚥下障害など多様な症状が出る」は英語で「Brain damage can cause the person to display symptoms such as: loss of consciousness, paralysis, and dysphagia (difficulty swallowing)..」と言います。
もし、英文にて「脳卒中などによって、脳にダメージをうけり」と追加したいなら、上記の英文の前に「A stroke can cause brain damage.」を置きます。そうすると、「A stroke can cause brain damage. Consequently, brain damage can cause the person to display symptoms such as: loss of consciousness, paralysis, and dysphagia (difficulty swallowing).」という風に言えます。
ご参考になれば幸いです。
