Catatonia in Sjögren's Syndrome

Out on Pubmed, from clinicians in Japan, is this case report:

 Case of Prolonged Catatonia Caused by Sjögren's Syndrome.

Inagaki T, Kudo K, Kurimoto N, Aoki T, Kuriyama K.Case Reports Immunol. 2020 Nov 3;2020:8881503. doi: 10.1155/2020/8881503. eCollection 2020.PMID: 33204547 
The pdf is here.
And from the text:
[This 58-year old woman]...received a 20-session course of ECT within a period of 10 weeks. (there were no adverse effects that interfered with the treatment, except for minor temporal delirium. Her catatonia was obviously improved along with the other depressive symptoms, including appetite loss and decline in locomotor activity. One week after the final ECT session, her pressure sores had completely resolved, and we were able to collect cerebrospinal fluid through a lumbar puncture for cytological examination. (results showed an increased cell count (10/μL), elevated IgG levels (14.3 mg/dL), and elevated interleukin-6 levels (5.14 pg/mL). (specific gravity and protein levels were within the normal limits. Based on these observations, we confirmed the diagnosis of neuropsychiatric SS [Sjogren's Syndrome]. Following steroid pulse therapy, she has not experienced catatonia for more than 5 years without the need for psychiatric treatments (e.g., antidepressants and ECT).

This is a straightforward case report of catatonia occuring in the context of a chronic autoimmune disorder. No details of the ECT were provided, other than the number of treatments.
I did learn a new word from the text of the case report: albocinereous. It means, "referring to both the white and gray matter." It derives from the latin for "white"  and "ashes".
