Diseases which affect your brain are quite bizarre in terms of quantifying the effects. I have some lesion damage from multiple sclerosis, but there's very little information available on what effects, if any I'd be able to identify. It's quite a bizarre experience to have physical damage that manifests in such a way that the entire outcome is subjective (was not putting clothes in the dryer an effect of Alzheimers? maybe), though clearly in this case the results are later measurable as the disease progresses. Nerve damage lower in the spine is easier to make judgements about, but still not perfect (for me this manifests as sensation loss, which is only measurable by stabbing me with a needle and asking how it felt). Though obviously unobtainable, I wish there was better ways of measuring cognitive damage than drawing overlapping pentagons, though I seem to be able to pass that one with my own evaluation despite lack of drawing skills.
