We report the case of a 54-year-old right-handed man who presented with a 2-year history of progressive upper-limb weakness with mild dysarthria and prominent involuntary perioral abnormal movements that were characterized as fasciculations. Electromyography disclosed motor neuron disease. The diagnosis of Kennedy's disease was established by polymerase chain reaction. Perioral abnormal movements and fasciculations may represent important clinical clues to the diagnosis of Kennedy's disease, particularly when associated with proximal muscle atrophy and gynecomastia. In suspected cases, genetic testing for elevated CAG repeats in the androgen receptor Xq12 gene is warranted.

Motor neurone disease (MND) is a neurodegenerative disease defined by axonal loss and gliosis of upper and lower motor neurones in the motor cortex, lower brainstem nuclei and ventral horn of the spinal cord. MND is currently incurable and has a poor prognosis, with death typically occurring 3 to 5 years after disease onset. The disease is characterised by rapidly progressive weakness leading to paralysis, fasciculations, bulbar symptoms (including dysarthria and dysphagia) and respiratory compromise. Respiratory complications arise as a result of weakness of upper airway (pharyngeal and laryngeal) muscles and respiratory muscles (diaphragm, intercostal and accessory muscles) leading to respiratory failure. Due to early involvement of respiratory muscles in MND, sleep disordered breathing (SDB) occurs at a higher frequency than compared to the general population. SDB usually precedes daytime respiratory symptoms and chronic respiratory failure. It significantly impacts upon patients' quality of life and survival and its presence may predict prognosis. Managing SDB in MND with non-invasive ventilation (NIV) improves quality of life and survival. Early identification and management of SDB in MND patients is therefore crucial. This update will review assessments of respiratory muscle function, types of SDB and the effects of NIV in patients with MND.

We describe a 64-year-old woman, suffering from late-onset obsessive-compulsive disorder (OCD) from the age of 57, who developed dysarthria and dysphagia, spastic diplegic, and proximal muscles weakness. Needle electromyography showed no active denervation. Neuropsychological evaluation showed intact cognitive functioning. We diagnosed upper motor neuron disease (MND), with no known genetic correlates. Brain magnetic resonance (MRI) detected bilateral hippocampal atrophy with sclerosis of right hippocampus. 18F-FDG positron emission tomography (PET) showed moderate right temporal cortex thinning. Six months later, motor and behavioral symptoms worsened. Neuropsychological examination revealed long-term memory deficit and executive dysfunction. MRI and PET evidenced severe worsening of atrophy in temporal and frontal lobes. Four years later a definitive diagnosis of primary lateral sclerosis (PLS) and FTD was made. To our knowledge, this is the first report of PLS and FTD with OCD at onset.

The X-linked spinal and bulbar muscular atrophy (Kennedy's disease) is a rare X-linked, recessive, lower motor neuron disease, characterized by weakness, atrophy, and fasciculations of the appendicular and bulbar muscle. The disease is caused by an expansion of the CAG repetition in the androgen receptor gene. Patients with Kennedy's disease have more than 39 CAG repetitions. We report a case of 57-year-old man, resident of Monte Dourado (PA, Brazil) who complained of brachiocrural paresis evolving for 3 years along with fasciculations and tremors of extremities. In addition, he also developed dysarthria, dysphagia, and sexual dysfunction. The patient clinical picture included gait impairment, global hyporeflexia, proximal muscle atrophy of upper limbs, deviation of the uvula to right during phonation and tongue atrophy with fasciculations. The patient reported that about 30 years ago he had undergone gynecomastia surgery. His electroneuromyography suggested spinal muscular atrophy, and nuclear magnetic resonance imaging showed tapering of the cervical and thoracic spinal cord. Patient's creatine kinase level was elevated. In view of the findings, an exam was requested to investigate Kennedy's disease. The exam identified 46 CAG repetitions in the androgen receptor gene, which confirmed the diagnostic suspicion. This was the first case of Kennedy's disease diagnosed and described in the Brazilian Amazon. To our knowledge only other four papers were published on this disease in Brazilian patients. A brief review is also provided on etiopathogenic, clinical and diagnostic aspects.

Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease, leading to progressive paralysis, dysarthria, dysphagia, and respiratory disabilities. Therapy is mostly focused on palliative interventions. During the course of the disease, verbal as well as nonverbal communicative abilities become more and more impaired. In this light, communication has been argued to be "the essence of human life" and crucial for patients' quality of life. High-tech augmentative and alternative communication (HT-AAC) technologies such as eyetracking based computer devices and brain-computer-interfaces provide the possibility to maintain caregiver-independent communication and environmental control even in the advanced disease state of ALS. Thus, they enable patients to preserve social participation and to independently communicate end-of-life-decisions. In accordance with these functions of HT-AAC, their use is reported to strengthen self-determination, increase patients' quality of life and reduce caregiver burden. Therefore, HT-AAC should be considered as standard of (palliative) care for people with ALS. On the other hand, the supply with individually tailored HT-AAC technologies is limited by external and patient-inherent variables. This review aims to provide an overview of the possibilities and limitations of HT-AAC technologies and discuss their role in the palliative care for patients with ALS.

A 52-year old woman first noted dysphagia four months before admission followed by dysarthria two months later. She then developed weakness of all limbs and became unable to walk. All these symptoms, associated with tongue atrophy, slowly progressed, leading to the initial clinical impression of a motor neuron disease, although her nerve conduction study and electromyography showed no abnormalities. Her brain MRI with T2 weighted/diffusion weighted image (DWI)/fluid attenuated inversion recovery (FLAIR) revealed a high signal lesion located at dorsal medulla oblongata. She proved positive for anti-aquaporin 4 antibody, which confirmed the diagnosis of neuromyelitis optica spectrum disorders (NMOSD). We conclude that NMOSD may initially present with progressive bulbar palsy and pyramidal tract disorder over a few months, mimicking a motor neuron disease. Awareness of this atypical presentation helps establish an early diagnosis of this treatable entity.

One-third of patients with amyotrophic lateral sclerosis (ALS) present with bulbar symptoms, exhibiting progressive dysphagia and dysarthria. In comparison, squamous cell carcinoma (SCC) of the tongue can cause tongue paralysis secondary to hypoglossal nerve infiltration. In rare cases, SCC can mimic motor neuron disease. Here, we describe a patient with SCC of the base of the tongue related to human papillomavirus infection who was initially misdiagnosed with bulbar-onset ALS.
