Abnormal stiffening and extension of the neck is one of the probable signs of which disease?

Abnormal stiffening and extension of the neck points to progressive supranuclear palsy, a parkinsonian syndrome with strong axial involvement. In PSP, rigidity and dystonic posturing of the neck and trunk are prominent, often producing a fixed, extended neck (retrocollis). This axial rigidity contrasts with the patterns seen in other diseases: Alzheimer's disease is mainly cognitive, Huntington's disease features chorea and psychiatric symptoms, and Parkinson's disease typically has tremor and bradykinesia with a better response to dopaminergic therapy, without the distinctive neck extension seen in PSP. Thus, the neck posture described best fits progressive supranuclear palsy.
