Within three months of having a TIA [mini-stroke], about 10% to 15% of people will have an actual stroke." That means that, if you have had a mini-stroke in the fall, you have better than a 1 in 10 chance of having a big stroke before winter is over. Maybe just in time for Christmas....
The good news is that "chances of preventing a major stroke with the appropriate treatments following a TIA are excellent". But only if you seek medical attention right away, and follow through "with the treatments and recommendations" of your health care providers.
It means making extra trips to the doctor's office. As many as you need. It means making sure the doctor understands you. It means making sure you understand everything the doctor wants you to do.
It means getting exercise, getting out in the sunlight, and improving your diet.
It means doing your own reasearch, so you can understand what is going on in your body. You are in charge of your own health.
There is plenty of information available about strokes. For example, there is the WebMD Stroke Health Center. You can even find Stroke Risk Calculators online, like this one from the UCLA Stroke Center.
