Memory Loss

It started with the typing errors.
Noticed I'd been transposing letters once in a while on words I type often... like my own name.
Then on other words.
And on a daily basis.

Never really thought I had a good memory.
Enjoyed chess, but couldn't think enough steps ahead and remember them to be good at the game.
If I didn't write instructions down, I'd forget something someone wanted me to do.

Once I'd had children, my brain went completely kablooey.
I joked that when I gave my children life, I also gave them brain cells.
Once the boys started school, I couldn't remember important dates and meetings anymore and started keeping a calendar.

But that's normal, right?

More recently, I thought it was the boredom that made my brain mushy.

After my recent colonoscopy and the drugs that erased my memory every 60 seconds until it stopped erasing my memory, it took more than what I thought should be a normal amount of time to stop forgetting things in short term.
But what was scary is, that feeling felt very familiar.

Twice since then, I've told a client at work that the boss was out of the office just moments before the boss came out of his office. 
"I thought I saw you leave."
"Yeah.  But I came back in.  You were right here."
Yup.  I was.  I was right there.

This morning, The Husband asked if I'd washed any t-shirts over the weekend.  I thought for a moment, remembered a pile of unwashed shirts next to the washer, and told him, "No, I didn't.  Do you want me to throw a load in now?"  He said I didn't have to, he'd make do.
A few minutes later, The Husband asked, "You didn't wash t-shirts?" then pointed to a basket in the livingroom filled with clean laundry.  His shirts were right on top.
::facepalm::
Tonight was the most bizarre, though.
Elder Son and I were watching TV downstairs when The Husband came down to say goodnight.
Not much later I heard odd noises.  Bumps. Thuds.  Elder Son seemed not to notice.  Then there was a hissing kind of sound.
"What is that?" I asked.
"It's just the pipes."
Just the pipes?  Why is there water running through the pipes?  We're the only two people in the house.  The Husband just left.  Why isn't Elder Son concerned?

Well, crap, you guys.
I'd forgotten The Husband was upstairs getting ready for bed, brushing his teeth, flushing the toilet.

I. Forgot.

I thought he'd left.
Yeah?  Where exactly did I think he'd have gone at this time of night?
To work?  Grocery shopping?  Where?

The Alzheimer's testing center is in our office building.  The guy in charge there says there's a general guide to answering whether or not you have Alzheimer's. 
He says, if you can't remember where you left your keys, that's normal.  If you have keys in your hand and you can't remember what they're for, that's a problem.
If you're in the middle of a staircase and you can't remember if you're going up or coming down, that's normal.  If you're in the middle of a staircase and you can't remember whose house you're in, that's a problem.
If you call one of your children by a sibling's name, that's normal.  If you don't remember having children, that's a problem.

I don't think I have Alzheimer's.
But I'm starting to think I have something.
