Objectives To address the prevalence and risk factors of suicidal outcomes in people with mild cognitive impairment or dementia. Methods Four databases were searched for studies reporting data on the prevalence or the risk of a suicidal event, in people with a clinical diagnosis of MCI or dementia. The research was conducted according to PRISMA guidelines. A narrative synthesis was used to report the main findings. A random effect model was used across all analyses to calculate the prevalence and the odds ratio of suicidal outcomes in people with dementia. Results Fifty-nine studies were included. The pooled prevalence of suicidal outcomes in people with dementia were as follows: suicidal ideation: 9.7% (95%CI 6.7-13.9), suicide attempt: 0.8% (95%CI 0.3-2.4), and suicidal death: 0.2% (95%CI 0.1-0.4). People with dementia had an increased risk of suicidal ideation (OR 1.87, 95%CI 1.21-2.88) and suicide attempt (OR 2.4, 95%CI 1.24-4.65) but no significant increase in the risk of suicidal death. The heterogeneity was high for each outcome. The risk factors for suicidal death in dementia were younger age, recent diagnosis, previous mental health disorder, and frontotemporal dementia. The prevalence of suicidal ideation in MCI ranged from 5 to 17.6%, with a moderate increase in suicide attempts (HR 1.34, 95%CI 1.09-1.65) and no increase in suicidal death. Conclusions People with dementia frequently have suicidal thoughts and are at an increased risk of suicide attempts. Clinicians should be careful to identify those at higher risk in order to offer them supportive care and restrict their access to lethal means.

Encoding of speech modes and loudness in ventral precentral gyrus

Abstract The ability to vary the mode and loudness of speech is an important part of the expressive range of human vocal communication. However, the encoding of these behaviors in the ventral precentral gyrus (vPCG) has not been studied at the resolution of neuronal firing rates. We investigated this in two participants who had intracortical microelectrode arrays implanted in their vPCG as part of a speech neuroprosthesis clinical trial. Neuronal firing rates modulated strongly in vPCG as a function of attempted mimed, whispered, normal or loud speech. At the neural ensemble level, mode/loudness and phonemic content were encoded in distinct neural subspaces. Attempted mode/loudness could be decoded from vPCG with 94% and 89% accuracy for the two participants, and corresponding neural preparatory activity at 640 ms and 270 ms before speech onset enabled 80% decoding accuracy, respectively. We then developed a closed-loop loudness decoder that achieved 94% online accuracy in modulating a brain-to-text speech neuroprosthesis output based on attempted loudness. These findings demonstrate the feasibility of decoding mode and loudness from vPCG, paving the way for speech neuroprostheses capable of synthesizing more expressive speech.
