People assume that handwriting changes as you age. It is one of the most common misconceptions I encounter. The truth is more precise than that, and it matters enormously in a forensic examination.

Handwriting is not handwriting. It is brainwriting.

Your signature is as individualized as your DNA, your fingerprints, or your voice. It comes from your brain, not your hand. And brains do not change simply because years pass.

My mother died at 97 and a half years old. Her handwriting in her final years was essentially identical to her handwriting from fifty years earlier. Age alone did not change it.

What changes handwriting is anything that alters the brain or the body. Medication. Alcohol. Disease. Physical injury to the hand, fingers, arm, or shoulder. If you alter what produces the writing, the writing changes. If you do not, it stays remarkably consistent across decades.

I demonstrate this with alcohol. Take a person’s signature when they are sober. Have them sign again after one drink, then another, then a third. By the third drink, the signature begins to deteriorate. The brain is altered, and the writing reflects it immediately.

This matters in an examination because I need to know who I am dealing with. What was the age of the person who signed this? What was their health at the time? Were they on medication? Did they have a physical condition affecting their hand? A good examiner investigates the human being, not just the document. That investigation is what makes the opinion reliable.

Frequently Asked Questions

Does handwriting change as you age?

Not from age alone. Handwriting is brainwriting — it comes from your brain, not your hand — and brains do not change simply because years pass. It stays remarkably consistent across decades.

What actually changes a person’s handwriting?

Anything that alters the brain or the body: medication, alcohol, disease, or physical injury to the hand, fingers, arm, or shoulder. Alter what produces the writing, and the writing changes.

Is a signature really as unique as DNA?

Your signature is as individualized as your DNA, your fingerprints, or your voice. Even so, no one signs exactly the same way twice — natural variation is part of authenticity.

Why does an examiner ask about health and medication?

Because a good examiner investigates the human being, not just the document — the signer’s age, health, medication, and physical condition at the time. That investigation makes the opinion reliable.
