I think he means that he doesnāt feel totally crazy. š The window of coherenceāreferring to the brainās ability to integrate cognitive and emotional information (neural coherence) and an individualās āsense of coherenceā (psychological coping)āis frequently disrupted. PD involves both a narrowing of functional brain connectivity (neural) and a reduced capacity to manage emotional and cognitive demands, leading to deficits in emotional regulation and increased apathy or depression.

Cognitive and Emotional Regulation Challenges in PD
Reduced Neural Coherence: Studies show that PD patients exhibit lower inter-hemispheric EEG coherence in theta, alpha, beta, and gamma frequency bands during emotional processing, particularly when dealing with negative emotions (fear, sadness, disgust).
āSense of Coherenceā (SOC) and Coping: A lower Sense of Coherenceāmeaning a reduced ability to manage stress or feel that life is manageableāis common in PD. A lower SOC directly correlates with higher depression and poorer quality of life, as patients may struggle to adapt to the diseaseās constraints.
Emotional Processing Deficits: Patients often have trouble identifying facial emotions and recognizing emotional prosody (tone of voice), which hinders social communication.
Cognitive Load and Emotion: When emotional regulation is required alongside high cognitive demands (e.g., in complex tasks), PD patients often experience āoverload,ā which leads to greater difficulties in processing information compared to healthy adults.
