    Background: Blogs have become a major venue of information sharing and emotional release for people worldwide. Illness blogs are a specific type of blog in which patients describe their experience with illness and coping with disease. Illness blog research has been conducted on several disorders; however, blogs by Parkinson's disease (PD) patients have been neglected.

    Objectives: To categorize the characteristics of PD patients from blogs and explore whether we can learn about the medical issues with which they are most concerned, as conveyed through their blog posts.

    Methods: Using located PD patients' blogs, we analyzed the contents of 78 blogs, and employed thematic analysis of eight arbitrarily selected blogs.

    Results: The majority of blog authors in our sample (N=78) were from the United States (42%). The number of blogs written by male and female authors was fairly similar: 49% and 44%, respectively, while gender was unknown for 7%. Blogs were written by both early- and late-onset PD patients. The thematic analysis revealed five major themes: diagnosis, symptoms, treatment, coping mechanisms, and information.

    Conclusions: Thematic analysis of blogs by PD patients provided considerable information and insight regarding the experience of these patients, which is significant to other patients and their families, as well as to medical professionals. Further qualitative studies of larger blog samples utilizing data mining techniques are needed to further explore the subjective experiences of patients.

    Background: While myoclonus and ataxia are considered common in patients with familial Creutzfeld-Jakob disease (fCJD), other movement disorders are less prevalent.

    Objectives: To systemically evaluate the frequency of extrapyramidal signs and movement disorders in patients with fCJD.

    Methods: A detailed neurological examination, with special emphasis on movement disorders and extrpyramidal signs, was conducted in 43 consecutive symptomatic CJD patients (26 males and 17 females mean age 58.7 ± 8.9 yrs, range 43–77 years) carrying the E200K mutation in the PRNP gene.

    Results: Limb or gait ataxia was noted in 38 patients (88%) (37 patients, 86%, had ataxia at presentation). Myoclonus was evident in 25/43 patients (58%) (21 patients, 49%, at presentation). In 95% of the patients (41/43) (37/43, 86% at presentation) at least one extrapyramidal sign throughout the disease course was noted, the most prevalent being rigidity (28/43, 65% of the patients and 22/43, 51% at presentation), followed by the glabellar sign (24/43, 56% of the patients and 22/43, 51% at presentation), bradykinesia (19/43, 44% and 15/43, 35% at presentation), dystonia (15/43, 35% 12/43, 28% at presentation) and tremor (13/43, 30% 12/43, 28% at presentation).

    Conclusions: In this unique population of fCJD patients, myoclonus was less prevalent than previously reported while other extrpyramidal signs were common and occurred at a relatively early stage of the disease. The high prevalence of movement disorders can be added to other phenomena characteristic of this familial disorder among Libyan Jews. Whether this is attributable to the E200K mutation itself or to some other mechanism has still to be elucidated.

    Objective: To report a unique hereditary, juvenile onset, craniocervical predominant, generalized dystonia and parkinsonism affecting four members of one family.

    Family Description: A father and three of his four daughters presented to us over the past 30 years with a similar picture of generalized dystonia, starting in the craniocervical region in the second or third decade of life. They later developed moderate parkinsonism, mainly manifesting bradykinesia, rigidity and abnormal postural reflexes. Biochemical and genetic tests excluded Wilson's disease, Huntington's disease and Oppenheim's dystonia.

    Conclusion: This is a new type of familial dystonia-parkinsonism where the craniocervical dystonic symptoms are most prominent in the early stages while parkinsonism becomes the predominant problem later in life. A search for the genetic mutation in this family is underway.
