My recurring symptom after b12 deficiency diagnosis four years ago is a recurring sequence of events:
Without warning, I will become semi conscious during which I will have tinnitus - the sound of static followed by a sense of euphoria and auditory hallucinations- I feel that I am overhearing a conversation which seems to make sense as it is occurring but makes no sense afterwards.
I am left in a state of confusion and my body feels stressed.
The events last no more than 10 seconds.
I will get up to 8 events on the first day then they decline to one or two a day then cease altogether.
Between 12 weekly injections I mostly get a five day period of the events in about week six to eight but in the last 36 weeks I have been getting the events soon after the injection as well.
The tinnitus stopped over two years ago and the auditory hallucinations only occur occasionally and the semi consciousness tends to last a matter of seconds on most occasions.
The article link above explains these events and what is known as metabolastic madness which is caused by b12 deficiency.
My mother had severe gastric problems and could not eat solid foods which, coupled with a lifetime of dieting, left her on a very restrictive diet. She developed Altzeimers disease and the article above explains why - for anyone feeling they are developing this disease or live with someone or has a parent who has the disease, I recommend end you read the article.
B12 injections, I hope, have saved me from my mother’s fate - my memory and articulacy were seriously affected until I started b12 injections and although not perfect (whose is at 70!) they are much better except I tend to lose track of distance in time relating to recent events.
I hope you find the article helpful.
