Record your scores at each timepoint. These tests measure attention, processing speed, memory, and executive function. Follow the standardised instructions each time for valid comparisons.
Visuospatial ability, executive function & memory · Scored 1–6 (Shulman scale)
The first test is called the Clock Drawing Test. This test gives us a window into several cognitive functions at once — your ability to plan, organise spatial information, and hold instructions in mind while you work. There are no tricks. I'll ask you to draw a clock, and then I'll score it using a standardised scale. Before we begin, please make sure there are no clocks or watches visible in the room.
Equipment: A blank sheet of white A4 paper · A pencil or pen · Remove all visible clocks or watches from the room before testing

Higher is better. A change of 1 point may be within normal variation. Persistent decline of ≥2 points warrants clinical review.
Processing speed (Part A) · Executive function & cognitive flexibility (Part B) · Time in seconds, lower = better
The next test is the Trail Making Test, and it has two parts. Part A tests how quickly your brain processes information — it's essentially a timed sequencing task. Part B adds an extra layer by asking you to switch between two types of information at the same time, which reflects a skill called cognitive flexibility. Both parts are timed from your first click, and they stop automatically when you finish. Errors won't stop you — just click the right target and keep going. There's no penalty for errors beyond the time they cost you.

Lower is better. Norms vary significantly by age and education level.
Lower is better. Practice effects can improve TMT scores over the first 2–3 sessions — interpret early improvements cautiously.
Processing speed · Average response time in ms (lower = faster)
This next test measures your reaction speed — specifically, how quickly your nervous system detects a signal and sends a response. It's called the Simple Reaction Time test. You'll complete five trials. The screen will turn green at a random moment, and your job is to tap it as quickly as you can when that happens. We use the average of your five responses. A couple of things to know: don't tap before the green appears — that trial won't count. And try to stay relaxed — tension actually slows reaction time. We want your natural speed, not your most effortful speed.

Enter in ms (e.g. 285). Lower is better.
Lower is better. A reduction of 30 ms or more is generally considered meaningful.
Semantic memory & executive retrieval · Words named in 60 seconds
This test is called the Category Fluency Test. It measures how quickly and efficiently your brain can search through stored memories and retrieve information — a function tied closely to semantic memory, which is the part of memory that holds general knowledge about the world. You'll have exactly sixty seconds. The timer and a counter will be visible on screen. Just focus on speaking as many words as you can.
Equipment: Stopwatch or phone timer · Pen and paper to record responses · Remove visible category cues from the room
Category: Use the same category at every session — Animals (most widely used), Fruits, or Supermarket items. Switching categories invalidates longitudinal comparison.

Norms based on Animals category (Tombaugh et al., 1999). Scores for Fruits and Supermarket are typically lower.
Higher is better. A change of ≥4 words is generally considered meaningful. Category fluency has moderate test-retest reliability — interpret changes cautiously.
Attention & working memory · Longest sequence correctly recalled
The final test is called the Digit Span, and it has two parts. The first part — Forward Digit Span — tests your attention and short-term memory. You'll hear a sequence of numbers, and repeat them back in the same order. The second part — Backward Digit Span — tests working memory, which is your brain's ability to hold information and mentally manipulate it. This time you'll repeat the numbers in reverse order. The sequences get longer as we go. The test stops when you miss both attempts at the same length — that's how we find your current span. I'll let you know when we switch from forwards to backwards.

Digits are read at 1 per second. Type immediately after the sequence finishes — no spaces needed. Stop rule: both trials at the same length must fail.

A change of ±1 span length is within normal variation. A reliable improvement requires a change of ≥2 span lengths.
