User:KeVFraNpar/Is there any 'hard' research substantiating 'Moon dementia'? prefix:Wikipedia:Reference desk/Archives

Recently my mother-in-law was being assessed by her local authority SSD with regard to her capabilities for independent living with support. Her regular carer commented on her behaviours and displayed emotions and that these were often agitation and anger. The mother-in-law has some short term memory disfunction. The involved community psychiatric nurse stated that the anger, agitation and erratic behaviours were, in his opinion, explainable due to 'Moon dementia'; Apparently a condition brought about by the waxing and waning of the moon and at its most disturbing at full moon.

I have not yet seen any hard statically related studies which would even indicate this condition exists and would welcome any information regarding reseach into this matter, as opposed to personal accounts of carers experiences. Thanks for any help you can offer.
