We live in times of rapid socio-cultural changes, and respective changes in the forms of mental suffering are increasingly characterized by fragmentariness and episodicity. These new forms of suffering may escape nosographic framing based on the identification of symptoms and syndromes. A paradigm shift in the psychiatric nosography is necessary. The way forward could be to enhance the ability of clinicians to grasp the \"fragments\" provided by patients rather than aggregations of symptoms. \"Existential knots\" can manifest themselves in these fragments to be used as \"floating buoys\" for clinical navigation, in the absence of exhaustive and detailed \"maps\" of the symptoms and syndromes that afflict patients.
