whacked round the head - memory loss

[mollykins]

I have several little questions for this;

~ can you lose your memory if your hit round the head with a badminton raquet?
~ would you have to have gone unconscience for you to lose part of your memory?
~ Is there a certain part of your head that you have to be hit upon to lose your memory (and if so which part)?

Because i was hit round the head (next to my left ear) with a raquet, i didn't go unconscience and and i can't remember much from the afternoon the day before onwards ( no i didn't have alcohol ect, just ibruprofen)

!)...very very unlikely.

2)...almost certainly.

3)....hippocampus for short term memory.

[mollykins]

where is the hippocampus?

[Sqad]

DEEP inside the temporal lobe of the brain.

By the way, it's unconscious NOT unconscience!

The history is fantastic for retrograde memory loss

so good, I would say, point made

are you trying to sue the arse of him ?
if so the lack of LOC - loss of consciousness - may prove a erm killer to your case

The natural history is that as tiime passes, you regain some but not all of the memory.
If it is subject to a legal claim the loss tends to be severe, disabling and permanent.

I googled head injury memory loss without loss of consciousness

and got a few zillion hits inc Ryu WH, who said:

OBJECTIVES: (1) To examine the variability in diagnosis of mild traumatic brain injury (mTBI) in primary care relative to that of an expert reviewer; and (2) to determine the incidence rate of mTBI in Ontario, Canada. METHOD: Potential mTBI cases were identified through reviewing three months of Emergency Department (ED) and Family Physician (FP) health records. Potential cases were selected from ED records using the International Classification of Disease, 9th revision, Clinical Modification and External Cause codes and from all FPs records for the time period. Documented diagnoses of mTBI were compared to expert reviewer diagnosis. Incidence of mTBI was determined using the documented diagnoses and data from hospital catchment areas and population census. RESULTS: 876 potential mTBI cases were identified, 25 from FP records. Key indicators of mTBI were missing on many records (e.g., 308/876 records had Glasgow Coma Scale (GCS) scores). The expert reviewer disagreed with the documented diagnosis in 380/876 cases (kappa = 0.19). The expert reviewer was more likely to give a diagnosis if the GCS was 13-14, if there was documented loss of consciousness and/or post-traumatic amnesia, and/or if there was pathology found on an acute brain scan. Calculated incidence rates of hospital-treated mTBI were 426 or 535/100,000 (expert review--hospital diagnosis). Including family physician cases increased the rate to 493 or 653/100,000. CONCLUSION: Health record documentation of key indicators for mTBI is often lacking. Notwithstanding, some patients with mTBI appear to be missed or misdiagnosed by primary care physicians. A more comprehensive case definition resulted in estimated incidence rates higher than previous reports.

and buried in that you will find:

The expert reviewer was more likely to give a diagnosis if the GCS was 13-14, if there was documented loss of consciousness and/or post-traumatic amnesia,

and the and/or bit means that memory loss without LOC is definitely recognised.

I doubt I will be sueing my dad . . .

I took a 90 minutes oral test at cadets the night before and all i could remember was doing the phonetic alphabet, knots, some saftey stuff and ranks & rates but i looked in book and saw that i must have done history of the corps, first aid, other health and safety stuff and lots of other seamanship . . .
