Akinetic mutism (AM) is a neurological disorder characterized by a profound lack of motivation, leading to severe motor and speech impairment or complete loss of function. Due to its clinical resemblance to disorders of consciousness and locked-in syndrome, AM is often misdiagnosed or overlooked, necessitating increased awareness among clinicians. This review summarizes the recent advances in neuroanatomical basis of AM, roles of neuroimaging in AM diagnosis and prognosis, and current therapeutic strategies of AM so as to enhance the awareness of clinicians in AM.

Disorder of consciousness is the dysfunction of recognition and awareness of the surrounding environment and its own state. In recent years, studies have shown that transcranial direct current stimulation has achieved considerable results in improving the disorder of consciousness. In this paper, the research progress on the neural bases of transcranial direct current stimulation for treatment of disorder of consciousness, comparison of different stimulation protocols and its value of differential diagnosis for levels of consciousness are summarized as follows.
