- Brief Summary
The main objective of this study is to evaluate the effect of metformin on the scores obtained in different cognitive subtests that make up the Unified Huntington's Disease Rating Scale (UHDRS) and that have been shown to be very sensitive to disease progression from early stages and even in the pre-symptomatic phase.

It is recommended that the carer be someone who attends the patient at least 2-3 times per week and for at least 3 hours per occasion. The suitability of the carer should be judged by the researcher.

A sum of > 4 points on the UHDRS-TMS scale and a diagnostic confidence level of 4.
Independence scale ≥ 75 %.

Name Time Method The tests that make up this subscale are the Symbol Digit Modalities Test, verbal fluency under phonetic command with the letters F, A and S, colour naming, word naming and interference in the Stroop test. The sum of the raw scores obtained makes up the UHDRS cognitive score, which is the primary endpoint of this study.
