Treating Huntington's disease

There's no cure for Huntington's disease. Its progress can't be reversed or slowed down, although this is the goal of many research projects.

Some of the features of Huntington's disease can be managed with medication and therapies, which may be coordinated by specialist teams.

Therapies, such as speech and language therapy and Occupational therapy , can help with communication and day-to-day living.

Regular exercise is also very important. People who are active tend to feel much better physically and mentally than those who don't exercise. Someone with Huntington's disease may have poor coordination, but walking independently, with the use of walking aids if necessary, can make all the difference.

However, it may sometimes be difficult to tell whether these are symptoms of the conditionor a result of the medication.

Antidepressants to treat depression

Antidepressants can helpimprove mood swings and treat depression . They include:

• SSRI antidepressants such as fluoxetine, citalopram andparoxetine
• tricyclic antidepressants such asamitriptyline
• other types of antidepressants including mirtazapine,duloxetine andvenlafaxine

Side effects of antidepressants may include:

• constipation
• sweating
• shaking or trembling
• difficulty sleeping ( insomnia )

Mood stabilisers to treat irritability or mood swings

Mood stabilisers, particularly carbamazepine,may be considered as a treatment for irritability.Olanzapine can also help, along with sodium valproate and lamotrigine.

The dose of carbamazepine needs to be slowly increased and any side effects monitored. Carbamazepine can't be used duringpregnancy.

Medication to suppress involuntary movements

The medications listed below suppress the involuntary movements or chorea seen in Huntington's disease. In the UK, antipsychotic medicines are usually preferred.

• antipsychotic medication such as olanzapine, sulpiride,risperidone andquetiapine
• tetrabenazine reduces theamount of dopamine reaching some of the nerve cells in the brain
• benzodiazepines such asclonazepam anddiazepam

Antipsychotic medication may also help control delusions and violent outbursts. However, they may have severe side effects, such as:

• stiffness and rigidity
• sedation
• tremor (shaking)
• moving slowly

Due to the possibility of experiencing these side effects, the lowest possible dose of antipsychotics are normally prescribed in the first instance.
