Introduction:
Chronotaraxis is an impairment of the perception of the sequencing of time. This alteration of temporality has been described as being characteristically associated with thalamic involvement, specifically in the dorsomedial nucleus.
Case Reports:
We report the clinical cases of two patients with acute ischaemic strokes located in said territory, with a clinical presentation based on this symptom and the recognition of which was essential in the therapeutic approach. In the first and second cases, it is described how the perception of temporality was essential for the diagnosis of the ischaemic condition in both patients.
Discussion:
Awareness and dissemination of this association may be vital in the management of patients with thalamic disorders. This is due to the possibility of influencing and modifying the initial approach, since the recognition of a specific symptom, such as chronotaraxis, can prevent the spread of thalamic damage, in addition to the long-term sequelae that it causes, especially those of a cognitive nature.
