Diagnosis of amyotrophic lateral sclerosis (ALS) takes more than 1year from detection of first symptoms. The paper seeks to understand the ALS diagnostic process and adjustment from the perspective of informal caregivers.

The data stems from an interview study with 9 current and 13 bereaved informal caregivers of people with ALS in Switzerland. The interviews were analyzed using thematic analysis.

We identified 3 key themes pertaining to ALS diagnosis. In the first theme, we present the close involvement of informal caregivers in the “diagnosis journey.” Highlighted within this theme is the important role they play, which ultimately leads to diagnosis of ALS avoiding further delays. Second, we relay their perceptions on “diagnosis communication pitfalls” where they underlined empathy and planning from the part of medical professional, while communicating the terminal diagnosis of ALS. Participants’ reactions and adjustments post-ALS diagnosis are described in “the aftermath of diagnosis.” In this third theme, we highlight participants’ shock and their need to rethink overall life plans and roles in their family.

Diagnosis communication that is clear, empathetic, and adjusted to the needs of the patients as well as their caregivers is critical. More work is needed to improve diagnosis communication for ALS patients. Receiving the diagnosis of ALS leads to complete changes in life of caregivers. It is therefore necessary that medical professionals provide adequate support that allows them to plan for their future.
