you may enjoy sections of Sami Schalk’s Black Disability Politics and it may be helpful to your efforts in finding people who write on this subject; here is one excerpt for example that i noted in my recent read-through of it:

On December 31, 1977, the Black Panther published a guest commentary article titled “Principles of Radical Psychiatry” by Claude Steiner, a white founder and practitioner of radical psychiatry. The article opens with a quote by Malcolm X and then asserts that “psychiatry is a political activity” because “the psychiatrist has an influence in the power arrangements of the relationships in which he intervenes.” Steiner argues that psychiatry and the psychiatrist can never be neutral because “when one person dominates or oppresses another, a neutral participant—especially when he is seen as an authority—becomes a participant in the domination.” Steiner goes on to state that psychiatry’s false and oppressive claim to neutrality makes marginalized people rightfully avoid psychiatric services. He then offers the alternative of radical psychiatry, writing, “A radical psychiatrist will take sides. He will advocate the side of those whom he is helping. The radical psychiatrist will not look for the wrongness within the person seeking psychiatric attention: rather, he will look for the way in which this person is being oppressed.”
