Perhaps you should try some spelling variations:
"motor neurone disease" » "motor neuron disease", "motor neuronal disease"
"motor neuronse disease" » "motor neuronal disease", "motor neuron disease", "motor neuronale disease"
"motor neuronale disease" » "motor neuronal disease"
"motor neurons disease" » "motor neuronal disease"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("motor neurone disease") or ((("motor neuronse disease") OR ("motor neuronale disease"))))) or ("motor neurons disease"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("motor neurone disease") OR ((("motor neuronse disease") OR ("motor neuronale disease"))))) OR ("motor neurons disease")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"motor neurone disease\") or (((\"motor neuronse disease\") OR (\"motor neuronale disease\"))))) or (\"motor neurons disease\"))".
• Removing quotes may allow a broader search: (((( motor neurone disease ) or ((( motor neuronse disease ) OR ( motor neuronale disease ))))) or ( motor neurons disease )).
• Adding a wildcard symbol may retrieve word variants: (((("motor neurone disease") or ((("motor neuronse disease") OR ("motor neuronale disease"))))) or ("motor neurons disease"))*.
