When a parent falls at night, the fall often happens on the same short walk, usually from the bed to the bathroom. The problem is rarely the whole house. It is a few steps, taken in the dark, at the moment a person is least steady. Knowing that lets you focus your effort on the right stretch of floor.

The signs that the walk is the problem
Look at your notes. If the falls happen when she gets up quickly, when the room is dark, when she is hurrying, or when she reaches out to a wall, door frame, or nightstand as she goes, the walk is probably where the trouble is. If you find her on the bed side or the bathroom side of the route, the route is involved. If she says she got up to use the bathroom, the bathroom trip is involved.
Keep a short log for two weeks
For each night she gets up, write down the time, where she was going, whether the lights were on, and whether anything felt off before she moved. Two weeks of short notes will show patterns that memory will not. Bring the log to her appointments, because it is the most useful thing you can give her doctor.
What the log cannot tell you
A log shows where and when. It does not show why. Whether dizziness, a medicine, a sleep problem, or a change in strength is part of the cause is a clinical question. Take those questions to her physician, and do not make a medicine change based on anything written here or on a caregiver's guess.
What to do after a fall
If she has fallen, check on her first, and follow the steps on the first ten minutes after a fall page. Then go back to the walk with your log in hand and look at the stops she passed through just before she went down.
