Do brain implants (like DBS) change your personality?

[jackedmonston]

From the New Yorker Magazine

For the great majority of patients, deep-brain stimulation was beneficial and life-changing, but there were occasional reports of strange behavioral reactions, such as hypomania and hypersexuality. Then, in 2006, a French team published a study about the unexpected consequences of otherwise successful implantations. Two years after a brain implant, sixty-five per cent of patients had a breakdown in their marriages or relationships, and sixty-four per cent wanted to leave their careers. Their intellect and their levels of anxiety and depression were the same as before, or, in the case of anxiety, had even improved, but they seemed to experience a fundamental estrangement from themselves. One felt like an electronic doll. Another said he felt like RoboCop, under remote control.

A little father down in the article is this:

He suspected that people whose marriages broke down had built their identities and their relationships around their pathologies. When those were removed, the relationships no longer worked.

As with many things, the outcome may not better or worse, just different.

Abstract

T he idea that deep brain stimulation (DBS) induces changes to personality, identity, agency, authenticity, autonomy and self (PIAAAS) is so deeply entrenched within neuroethics discourses that it has become an unchallenged narrative. In this article, we critically assess evidence about putative effects of DBS on PIAAAS. We conducted a literature review of more than 1535 articles to investigate the prevalence of scientific evidence regarding these potential DBS-induced changes. While we observed an increase in the number of publications in theoretical neuroethics that mention putative DBS-induced changes to patients’ postoperative PIAAAS, we found a critical lack of primary empirical studies corroborating these claims.

While we observed an increase in the number of publications in theoretical neuroethics that mention putative DBS-induced changes to patients’ postoperative PIAAAS, we found a critical lack of primary empirical studies corroborating these claims. Our findings strongly suggest that the theoretical neuroethics debate on putative effects of DBS relies on very limited empirical evidence and is, instead, reliant on unsubstantiated speculative assumptions probably in lieu of robust evidence. As such, this may reflect the likelihood of a speculative neuroethics bubble that may need to be deflated. Nevertheless, despite the low number of first-hand primary studies and large number of marginal and single case reports, potential postoperative DBS changes experienced by patients remain a critical ethical concern. We recommend further empirical research in order to enhance theoretical neuroethics work in the area. In particular, we call for the development of better instruments capable of capturing potential postoperative variations of PIAAAS.

I find medications affect personality. And nutrient deficiencies therefore supplements too. There is lots of research on various brain conditions and nutrition. So it’s not surprising.
